Well the formula for the quadratic equation is y = -b + √b² - 4ac / 2a
Fill in the variables with the information where a = 2, b = 2, and c = -12.
The final answer is y = -2 + √2² - 4(2)(-12) / 2(2)
A simplified answer would be y = -2 + √4 + 96 / 4, which further simplifies to
y = -2 + 10 / 4
This can be simplified into two answers, either y = -3 or y = 2
