Question

Solve the following equation for x.
0 = 6x2 + 54x + 120
а
X = 5
b
X = -10
C
x = -5 and x = -4
O a
d
x = -10 and x = -2

Answer 1

Answer:

c

Step-by-step explanation:

6x² + 54x + 120 = 0

divide by 6

x² + 9x + 20 = 0

(x² + 5x) + (4x + 20) = 0

x(x + 5) + 4(x + 5) = 0

(x + 4) (x + 5) = 0

x + 4 = 0, x + 5 = 0

x = -4, x = -5
