Answer:
x = -2
x = -10
Step-by-step explanation:
Given: 3x^2+36x=-60
First, transform the quadratic equation into standard form:
standard form: ax² + bx + c = 0
3x² + 36x + 60 = 0
a = 3
b = 36
c = 60
then substitute a, b and c to the quadratic formula:
Quadratic formula: x = -b ± √(b² - 4ac) / (2a)
x = {-36 ± √(36)² - 4(3)(60) }/ 2(3)
x = -36 ± √(1296 - 720) / 6
x = -36 ± √(576) / 6
x = -36 ± 24/ 6
x = -6 ± 4
x = -6 + 4 = -2
or
x = -6 -4 = -10
