Question

(4+x)^2-2x factorize thus question
​

Answer 1

Step-by-step explanation:

on opening the sq

x^2+(4)^2+ 2*4*X -2x

= x^2 +6x +4

using quadratic formula

D= b^2-4ac

= 36-16

√D = 2√5

roots = -b+√D/2a , -b-√D/2a

roots of the eq = -6+2√5/2 , -6-2√5/2

so the roots of the eq is 3+√5 ,3-√5
