4x^3-8x^2-9x+18
X(4x^2-8x-9)+18
Answer:
<em>The number is -6.</em>
Step-by-step explanation:
Let x = the unknown number
"the sum of a number and four" = n + 4
"Six times the sum of a number and four" = 6(n + 4)
"Six times the sum of a number and four is -12." is the equation
6(n + 4) = -12
Divide both sides by 6.
n + 4 = -2
Subtract 4 from both sides.
n = -6
