Question

Factorise 5 y square + 5 y - 10

Answer 1

5y²+5y-10

5y²+10y-5y-10

5y (y+2) - 5(y+2)

(5y-5) (y+2)

y=5/5 y= -2

y= 1 , -2

Answer 2

Answer:

5y^2+5y-10 = 5(y+2)×(y-1)

Step-by-step explanation:

5y^2+5y-10

Factor out 5 from the expression

5(y^2+y-2)

Write y as a difference

5(y^2+2y-y-2)

Factor out y from the expression

5(y×(y+2)-y+2))

Factor out y + 2 from the expression

5(y+2)×(y-1)

Hence, 5y^2+5y-10 = 5(y+2)(y-1)

Hope it Helps!
