Answer:
Multiply both sides of the equation by 1/3
Step-by-step explanation:
3x^2+18x=21
The first step is to get the x term with a coefficient of 1, so divide by 3 on both sides of the equation
This is the same as multiplying by 1/3
1/3 * (3x^2+18x)=21*1/3
x^2 +6x = 7
Answer:
X^2-x-12
Step-by-step explanation:
FOIL
First, Outside, Inside, Last
First: X*X=X^2
Outside: x*-4=-4x
Inside: x*3=3x
Last:3*-4=-12
All together: X^2-4x+3x-12
Simplify: X^2-x-12
