Question

1) a verify : x² + 4x+3 = (x+2) ²)​

Answer 1

undefined

Explanation:

x²+4x+3 = (x+2)²

first of all you open the bracket on the Right hand side..

(x+2)² = (x+2)(x+2)

= x(x+2)+ 2(x+2)

=x²+2x+ 2x+4

= x²+4x+4

therefore,

x²+4x+3 = x²+4x+4

next, we collect all like terms together,

x²-x²+4x-4x = 4-3

0+0 = 1

the answer is undefined

because 0 cannot be equal to 1

Answer 2

NO

Explanation:

X^2+4X+3=(X+2)(X+2)

X^2+4X+3=X^2+2X+2X+4

X^2+4X+3=X^2+4X+4
