Mathematics

Complete factor: (2x+7)(2x+7)

C is correct.

Step-by-step explanation:

Given: 4x^2+28x+49

Factor the polynomial completely

$\Rightarrow 4x^2+28x+49$

make perfect square first and last term

$4x^2\rightarrow (2x)^2$

$49\rightarrow 7^2$

$\Rightarrow (2x)^2+2\cdot 2x\cdot 7+7^2$

Factor formula:

a^2+2ab+b^2=(a+b)^2=(a+b)(a+b)

Compare the given polynomial with formula and factor it.

$a\rightarrow 2x$

$b\rightarrow 7$

$\Rightarrow (2x)^2+2\cdot 2x\cdot 7+7^2=(2x+7)^2$

In complete factor form, (2x+7)(2x+7)
