Question

4y square + y - 45 when y=-5

Answer 1

Given:

The expression is

`4y^2+y-45`

To find:

The value of the given expression when y=-5.

Solution:

We have,

`4y^2+y-45`

Putting y=-5, we get

`4(-5)^2+(-5)-45`

`=4(25)-5-45`

`=100-50`

`=50`

Therefore, the value of the given expression is 50 when y=-5.
