Question

Solve this equation by factorising:
y² + 3y - 10 = 0

Answer 1

y = 2

Explanation:

Answer 2

first of list factors of 10
1 10
2 5

-2 and 5 can add up to get -3
so you would place it into brackets
(y-2)(y+5)=0

now work with each bracket at a time:
y-2=0
y=2

and the next one:
y+5=0
y=-5

and here is what you get
y = -5, 2
