Question

given the expression $3(x - 5)^2 + 12$, what is the equivalent expression in standard form? $square x^2 square x square$ (include +/- to seperate the terms.)

Explanation:

Step1: Expand $(x-5)^2$

$(x-5)^2 = x^2 -10x +25$

Step2: Multiply by 3

$3(x^2 -10x +25) = 3x^2 -30x +75$

Step3: Add the constant term

$3x^2 -30x +75 +12 = 3x^2 -30x +87$

Answer:

$3x^2 -30x +87$
