Question

Pls help me with 13 you will get Brainly the instructions are to evaluate the following a=6, b=3,c=2 please answer this question pls you will get Brainly for the best answer but please provide step-by-step explanation also

Answer 1

You have to plug in the values into the equation.

Since a=6, all the a's in the equation would be replaced by 6 and same goes for the b.

^ means exponent btw

= -[2(6)^2 -6- (5(6)^2-3(3)) -4(6)^2 +2(3)]

Calculate/ simplify

= -[2(36)-6 - (5(36) -9)-4(36)+6]

Multiply all the things in parenthesis

= -[72-6-(171)-144+6]

Add/subtract

= -[-243]

Negative times negative becomes positive therefore, the answer becomes 243
