Question

(x+5)(x-3)=y
How do I get y to equal 0

Answer 1

x=-5 or x=3

Explanation:

when you have (x+N) its its like saying x+n=0 so x=-n

Answer 2

x=-5 or x=3

Explanation:

when multiplying anything by 0, the answer will be zero

In this case, one of the two factors has to be equal to 0

start by splitting into

(x+5) = 0

solve the equation

subtract 5 from both sides

x = -5

now, repeat for the other binomial

x-3 = 0

add 3 to both sides

x=3
