Answer 1

I’m confused on the question but wouldnt it be (x+6) (x+6)

Answer 2

x = -6

Or

x = -6

Explanation:

x^2 + 12x + 36 = 0

Factorise

(x + 6)(x + 6) = 0

x + 6 = 0

Subtract 6 from both sides

x + 6 - 6 = 0 - 6

x = -6

Or

x + 6 = 0

Subtract 6 from both sides

x + 6 - 6 = 0 - 6

x = -6
