Question

x^2+3x-10=0 the solution(s) is/are x=?

Answer 1

-5 , 2

Answer 2

Find two numbers that multiply to -10 and add to 3. These two numbers are 5 and -2. So that gives us (x+5)(x-2)=0. Use the zero product property to then solve to get x+5=0 or x-2=0. We then get x=-5 or x=2

Answer 3

Factor the equation to get:

(x+5)(x-2)=0
x+5=0
x=-5

x-2=0
x=2
