Answer: the first one (x+4)^2

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

(x+4)^2 = x^2 + 8x + 4

Answer:

Option 1

Explanation:

Find 2 numbers that multiply to give 16 and sum to give +8 :

These numbers are 4 and 4

Now split +8x into +4x and +4x and factor each part :

x²+4x+4x+16 = 0

x(x+4)+4(x+4) = 0

Keep 1 bracket and the terms outside the brackets make their own :

(x+4)(x+4) = 0

(x+4)² = 0

Therefore answer will be Option 1

Hope this helped and have a good day
