What are the x-intercepts of y = 2x2 - 3x - 20?
a) x = -5 and 2
b) x = 5 and -2
c) x = -2.5 and 4
d) x = 2.5 and -4

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
