Question

What are the x-intercept(s) of the graph of y + 20 = x2 - x?

Answer 1

to find x-intercept make y=0 in the equation and solve for x

Answer 2

would you like some more explanations?

Answer 3

Yes please!!

Answer 4

so plug in y=0 into your equation, and you get quadratic equation like this: 20=x^2-x...if you rearrange it a little bit you get x^2-x-20=0 so your task is to find the solutions for x...do you know how to solve the quadratic equation, it's basic?

Answer 5

like you see in the point where the line cross x axis the y coordinate is 0. That's why make y=0 in the equation to find corresponding x
