Find all of the points at which the parabolas below intersect. Write your solution(s) in (x, y) form. Homework Help ✎

y = x2x + 12
y = 2x2 + 3x + 7

Set the equations equal to each other.

x² - x + 12 = 2x² + 3x + 7

Set the equation equal to zero.

0 = x² + 4x − 5

Factor the expresion.

Solve for x.

Substitute your answer for x back into the equation and
solve for y to find the points of intersection.
