Answer:
undefined
Step-by-step 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
