Question

Solve the equation 2p square + 11p=30

Answer 1

`p=- (15)/(2)`

`p=2`

Explanation:

`2p^2+11p=30`

Subtract 30 on both sides.

`2p^2+11p-30=30-30`

`2p^2+11p-30=0`

Factor left side of the equation.

`(2p + 15)(p-2)=0`

Set factors equal to 0.

`2p+15=0`

`2p=-15`

`p=(-15)/(2)`

`p-2=0`

`p=2`
