Answer:
6(x-5)2+288
Step-by-step explanation:
6x2-60x+438 Factor out a 6 from the first 2 terms.
6(x2-10x )+438 Do (b/2)2 to find the c term. (-10/2)2 = 25
6(x2-10x+25)+438-150 Adding 25 inside the parenthesis is really like adding 6(25)=150 to that side of the equation. To keep the equation in balance, you have to subtract 150 from the other term. Simplify
6(x-5)2+288
