Answer:
2x^3 +3x^2 +9x +3
Step-by-step explanation:
Polynomial long division works best with the polynomials written in standard form, with appropriate 0 terms added where necessary to account for all of the powers of the variable.
As shown in the "Hints," the quotient terms are the ratio of the leading dividend term and the leading divisor term. The product of the quotient term and divisor is subtracted from the dividend to get the new dividend at each step.
The result of your division is 2x^3 +3x^2 +9x +3.
Answer:
X = -15
Step-by-step explanation:
6X +12 = 4X -18
Subtract 4X from both sides
2X +12 = -18
Subtract 12 from both sides
2X = -30
Divide both sides by 2
X = -15
So basically just have the unknown on one side and normal numbers on the other. Make sure you do the same thing on both sides.
