# Which is the completely factored form of 4×2 28x 49

## What is the measure of a side of a square whose area is 4x² 28x +49 square units?

4x²+28x+49=(2x+7)² => Its side will be

**(2x+7)**a dependent variable on the value of x. Ans.. Since area of a square is equal to the (length of side)² therefore the length of the side of the square is 2x+7.## Which is the completely factored form of 12x 3 60x 2 4x 20?

Answer and Explanation: The answer is D.

**4(3×2+1)(x−5)**.## What is the factored form of the polynomial x2 9x +20?

The factored form of the polynomial x

^{2}+ 9x + 20 is**(x + 5)(x + 4)**.## What is the measure of one side of the square if its area?

Since we know the shape here is square, we know that all sides are of

**equal length**. From this we can work backwards by taking the square root of the area to find the length of one side. The length of one (and each) side of this square is 6 inches.## Which of the following is a perfect square number?

The first 12 perfect squares are: {1, 4, 9, 25, 36, 49,

**64**, 81, 100, 121, 144…} Perfect squares are used often in math.## What is the completely factored form of the expression 16×2 8x 32?

The factored form of the expression 16x

^{2}+ 8x + 32 is**8[2x**.^{2}+ x + 4]## What is the factored form of 8×2 12x?

4x

The factored form of the equation 8x

^{2}+ 12x is**4x( 2x + 3)**.## What is the factored form of x2 4x 5?

## What is the completely factored form of the expression?

## What is the completely factored form of x4 8×2 9?

The completely factored form of x

^{4}+ 8x^{2}– 9 is**(x + 3i)(x – 3i)(x + 1)(x – 1)**.## What is the completely factored form of xy3 x3y?

xy

The completely factored form of xy

^{3}– x^{3}y is**xy(y + x)(y – x)**.## What is the factored form of R 2 49?

Rewrite 49 as 72 . Since both terms are perfect squares, factor using the difference of squares formula,

**a2−b2=(a+b)(a−b) a 2 – b 2 = ( a + b ) ( a – b )**where a=r and b=7 .## What is the factored form of 125a 6?

Rewrite 125a6 125 a 6 as

**(5a2)3 ( 5 a 2 ) 3**. Rewrite 64 as 43 . Since both terms are perfect cubes, factor using the difference of cubes formula, a3−b3=(a−b)(a2+ab+b2) a 3 – b 3 = ( a – b ) ( a 2 + a b + b 2 ) where a=5a2 a = 5 a 2 and b=4 .## What is factored form?

Factored form,

**the product of a constant and two linear terms:****or**.**The parameters and are the roots of the function**(the x-intercepts of the graph ). Converting a quadratic function to factored form is called factoring.
