Question

Simplify the expression 2(a2+ab) +3 –ab and find its value when a = 5 and b = -3.

Answer 1

Answer : 8 (the step by step explanation is above ) :)

Answer 2

Answer:

Okay! Let's substitute the values.

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

Lets solve inside the brackets first (by applying bodmas)

=2[25+(-15)]+3- (-15)

=2(10-15)+3+15

=2(-5)+18

=(-10)+18

=8

There you go, hope you got it :)
