Answer 1

Answer:

5y²-5y-10 = 5y²+5y-10y-10

= 5y(y+1)-1(y+1)

= (5y+1)(y+1)

hope this helps....

Answer 2

Given:

A equation 5y²+5y-10

To find:

factor of the equation

Solution:

Given equation 5y²+5y-10

rewrite the equation

=5(y²+y-2)

=5(y²+2y-y-2)

=5{y(y+2)-1(y+2)}

=5(y-1)(y+2)

Hence, 5, y-1, y+2 are the factors of the equation 5y²+5y-10
