Evaluate the following expression if A) y=-3 B) y=2 12 {y}^(2) - 13y + 3

Question

Evaluate the following expression if A) y=-3 B) y=2

`12 {y}^(2) - 13y + 3`

Answer 1

to solve we can just enter in the values for y so

`12 ({ - 3}^(2) ) - 13( - 3) + 3 = 12(9) + 39 + 3 = 150`
same for 2

`12( {2}^(2) ) - 13(2) + 3 \\ = 12(4) - 26 + 3 \\ = 48 - 29 + 3 = 22`
