Question

What are the x-intercepts of the equation y = -2(x+3)(x-4) *

Answer 1

x = -3 and x = 4

Explanation:

x-intercept means where the equation touches the x-axis.

At x-axis line, value of y will be 0.

So, y = -2(x+3)(x-4)

becomes 0 = -2(x+3)(x-4)

Now,

x + 3 = 0

x = -3

x - 4 = 0

x = 4
