Which of the following points represents the x-intercepts of the quadratic equation y = x2 + 9x?
Question
Solution 1
The x-intercepts of a quadratic equation are the values of x when y = 0.
So, to find the x-intercepts of the equation y = x^2 + 9x, we set y = 0 and solve for x:
0 = x^2 + 9x
This is a quadratic equation, and we can solve it by factoring:
0 = x(x + 9)
