One x-intercept for a parabola is at the point (1,0). Use the factor method to find the other x-intercept for the parabola defined by this equation: y-5x^2+15x-10

Question

anonymous · Answer

To find the x-intercept, set y = 0 and solve for x. Since the polynomial has an order of 2, and crosses the x-axis, it will have two roots. Find the roots of the equation using the quadratic equation, factoring, or complete the square.

myininaya · Answer

y=5(x^2+3x-2)
0=5(x^2+3x-2)
0=x^2+3x-2
(1,0) is not an x-intercept
is your question written correctly?
