^{2}– 6x = 5) is**9**.## Which are the solutions of the quadratic equation x2 7x 4?

Summary: The solution of the quadratic equation x

^{2}= 7x + 4 is**x = [7 ± √65]/2**.## What are the solutions to the quadratic equation x2 16 0?

## How did you find the solution of the equation?

The process of finding the solution to an equation is called

**solving the equation**. To find the solution to an equation means to find the value of the variable that makes the equation true. … We say 5 is a solution to the equation x+2=7 x + 2 = 7 because when we substitute 5 for x the resulting statement is true.## What should be added to both sides of equation x2 2x 5 so that the LHS becomes a complete square?

**Take half of the coefficient of x and square it**. That is the number that should be added to both sides.

## What is the first step in solving the quadratic equation 8 133?

Adding 8 to both sides of the equation. Summary: The first step in solving the quadratic equation -5x

^{2}+ 8 = 133 is**to subtract 8 from both sides of the equation**.## How do you find all solutions?

## What are the solutions to the equation x2 6x 40?

The solutions to the equation x

^{2}+ 6x = 40 are**-10, 4**.## How many solutions does each equation have?

If solving an equation yields a statement that is true for a single value for the variable, like x = 3, then the equation has one solution. If solving an equation yields a statement that is always true, like 3 = 3, then the equation has

**infinitely many solutions**.## What are real solutions?

In chemistry, a real solution is

**a homogeneous mixture of at least two chemical substances**. A “real” solution differs from a colloidal solution (colloid). According to the concentration of the solute, a distinction is made between hypotonic solution, saturated solution, unsaturated solution.## What are all real solutions?

Frequently, in Algebra class, you will be called to find all “real solutions” of an equation. …

**Simplify the equation as much as possible**. For instance, if given the equation x4 + x2 – 6 = 0, you can use a u-substitution to simplify and then factor. If x2=u, then the equation becomes u2+u-6=0.## Is 0 a real solution?

0 is

**a root**, a solution, or a “zero”. Because 0 is a real number, we can call it a real root, a real solution, or a real zero.## How many real solutions are there?

2 real solutions

It determines the number and the type of solutions that a quadratic equation has. If the discriminant is positive, there are

**2 real solutions**. If it is 0 , there is 1 real repeated solution. If the discriminant is negative, there are 2 complex solutions (but no real solutions).## How many imaginary solutions are there?

## Which equation has only one solution?

An independent system has exactly one solution pair

**(x,y)**. The point where the two lines intersect is the only solution. An inconsistent system has no solution. Notice that the two lines are parallel and will never intersect.## How many solutions does quadratic equation have?

2 solutions

As we have seen, there

**can be 0, 1, or 2 solutions**to a quadratic equation, depending on whether the expression inside the square root sign, (b^{2}– 4ac), is positive, negative, or zero. This expression has a special name: the discriminant.## What are real solutions in algebra?

REAL SOLUTIONS means that

**expressions which have some real values OR**.**Solution containing real values**are called real solutions. Ex- 1,2,10,100 etc. Non real solutions means that the solutions containing non- real values like √2,√3 etc.
