Question

Identify the factors of 4x2+20x+25

Answer 1

The factors of given equation is (2x+5)^2

Step-by-step explanation:

$4x^{2} +20x+25$

= $(2x)^{2}$+ 2 X 2x X 5 + (5)^2

= (2x +5)^2

Here we have applied given formula

$(a+b)^{2} = a^{2} +2ab + b^{2}$

Taking a= 2x and b = 5 we get the answer.
