Q. (x−4)(x−8)Which of the following is equivalent to the given expression?Choose 1 answer:(A) x2−12x+32(B) 2x2+4x+32(C) x2+4x−12(D) 2x2−12x+32
Apply distributive property: Apply the distributive property (also known as the FOIL method for binomials) to multiply the first terms of each binomial. (x×x)=x2
Multiply outer terms: Multiply the outer terms of the binomials.(x×−8)=−8x
Multiply inner terms: Multiply the inner terms of the binomials.(−4×x)=−4x
Multiply last terms: Multiply the last terms of each binomial.(−4×−8)=32
Combine like terms: Combine the like terms from steps 2 and 3.−8x+(−4x)=−12x
Final expanded form: Add up all the results from steps 1, 5, and 4 to get the final expanded form. x2−12x+32
