Question

Plz help me get the answer to these

Answer 1

-9y - 4

Explanation:

`(45y^2+20y)/(-5y)=(45y^2)/(-5y)+(20y)/(-5y)=-9y-4`

Answer 2

- 9y - 4

factorise the numerator by taking out a common factor of 5y

45y² + 20y = 5y(9y + 4)

The expression now becomes

`(5y(9y+4))/(-5y)`

the 5y on numerator/ denominator cancel leaving

- (9y + 4) = - 9y - 4 ← quotient
