Question

Factorise completely Y²+Y-30

Answer 1

Answer:

(y+6)(y+5)

Step-by-step explanation:

y^2 + y - 30

Breaking the middle term:

y^2 + 6y - 5y - 30

y(y+6) + 5(y+6)

(y+6)(y+5)

Answer 2

Answer:

Y²+y-30

Multiply the first and the last

Which is Y²x 30

=30y²

Multiply factors. Divide factors

30y²= -5y+6y. -5y+6y= y the middle factor

y²+y-30

( y²-5y) +(6y-30)

y(y-5) 6(y-5)

(y-5). (y+6)
