Question

Using factor method, divide the polynomial (y2 - y - 42) by (y - 7).​

Answer 1

Answer: y + 6

Step-by-step explanation:

Answer 2

Answer:

(y2 - y - 42) / (y - 7)= y + 6

Step-by-step explanation:

We have to,

Divide the polynomial ( - y - 42) by (y - 7)

To find,  the divide the polynomial ( - y - 42) by (y - 7) = ?

By factors method,

∴ (y2 - y - 42) / (y - 7)

= (y2 - 7y-6y - 42) / (y - 7)

= y(y-7)+6(y-7)/ (y - 7)

= (y-7)(y+6)/ (y - 7)

The numerator and denominator having (y - 7) is cancel.

= y + 6

The divide the polynomial ( y2- y - 42) by (y - 7) = y + 6

Thus, = y + 6
