Question 849753: what are the x-interceps of y= 6x2 + 18x - 60
Answer by jim_thompson5910(35256)   (Show Source):
You can put this solution on YOUR website! Plug in y = 0 and solve for x.
y = 6x^2 + 18x - 60
y = 6(x^2 + 3x - 10)
0 = 6(x^2 + 3x - 10)
0/6 = x^2 + 3x - 10
0 = x^2 + 3x - 10
x^2 + 3x - 10 = 0
(x + 5)(x - 2) = 0
x + 5 = 0 or x - 2 = 0
x = -5 or x = 2
So the x-intercepts, as ordered pairs, are: (-5,0) and (2,0)
