Answer:
x = -12/6 = -2
x = -18/6 = -3
Step-by-step explanation:
The zeros in an equation is the same thing as the x's.
3x²+15x+18 = 0 (Where a = 3, b = 15, c = 18)
One thing you could do to find the answer is use the quadratic formula:
x = (-b ± √(b²-4ac))/2a =
(-15 ± √15² - (4*3*18))/2*3 =
(-15 ± √225 - 216)/6 =
(-15 ± √9)/6 =
(-15 ± 3) / 6.
To find the first x we need to do (-15 + 3) / 6 and to find the second x we need to do (-15-3) / 6.
x = -12/6 = -2
x = -18/6 = -3
