Solution

The x-intercepts of a quadratic equation are the values of x for which y = 0.

So, to find the x-intercepts of the equation y = x² + 5x + 6, we set y = 0 and solve for x:

0 = x² + 5x + 6

This is a quadratic equation in the form ax² + bx + c = 0, where a = 1, b = 5, and c = 6.

We can solve this equation by factoring:

0 = (x + 2)(x + 3)

Setting each factor equal to zero gives the solutions x = -2 and x = -3.

So, the x-intercepts of the equation y = x² + 5x + 6 are the points (-2, 0) and (-3, 0).
