What are the roots of y = x2 - 3x - 10?

0-3 and - 10

-2 and 5

X 2 and - 5

3 and 10

x = 5 x = - 2

Step-by-step explanation:

y = x^2 - 3x - 10

Set the equation equal to zero

0 = x^2 - 3x - 10

Factor

What 2 numbers multiply to - 10 and add to - 3

-5 * 2 = - 10

-5+2 = - 3

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

Using the zero product property

x-5 = 0 x+2 = 0

x = 5 x = - 2
