Explanation: A and C are wrong because a negative times a positive is a negative
And D is wrong because a positive times a positive is a positive
Perform indicated operations on left side
x*x+4x+4x+4*4=9
x^2+4x+4x+16=9 combine like terms on left side
x^2+8x+16=9 subtract 9 from both sides
x^2+8x+7=0 factor
x^2+x+7x+7=0
x(x+1)+7(x+1)=0
(x+7)(x+1)=0
x=-1, -7

Answer: Choice B) Distributive property
The 4 is distributed through the parenthesis
The outer term 4 is multiplied by each of the inner terms (x and -6)
4 times x = 4x
4 times -6 = -24
those results are then added up
So that's how 4(x-6) turns into 4x-24
