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

kobusy [5.1K]

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.
