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 defin
Hoochie [10]
First simplify the equation of parabola y=-5x^2+15x-10 in the following way:
D=(15)^2-4\cdot (-5) \cdot (-10)=225-200=25, \\  \sqrt{D}=5, \\  x_{1,2} = \dfrac{-15\pm 5}{2\cdot(-5)} = 2, 1  \\ -5x^2+15x-10=-5(x-1)(x-2), \\ y=-5(x-1)(x-2).
You can see that if x=1 or x=2, then y=0. Two points of intersection with x-axis are (1,0) and (2,0).

sergejj [24]

Answer:

First, let's make an expression!

If you meant a different equation..sorry

\frac{8+6}{7-3} +\frac{1}{2}

Hope this is what you meant!

\frac{14}{4} +\frac{1}{2}\\\frac{7}{2} +\frac{1}{2} \\\frac{8}{2} =4

Hope this helps!

P.S. Stay Safe!
