Answer: B x=+-2
Step-by-step explanation:
The Quadratic formula is -b+-
First make everything equal to 0

Then Simplify

Now use the formula where a=3, b=0, and c=-12
divided by 2(3)


then we get 12/6 and -12/6 which simplified is +-2

Answer:
x=2
Step-by-step explanation:
<u>Question: 4(2-x)+15=3(x+3)</u>
<u />
1) Distribute 4 to 2 and -x:
8-4x+15=3(x+3)
2) Distribute 3 to x and 3:
8-4x+15=3x+9
3) Combine alike terms:
23-4x=3x+9
4) Add 4x to both sides:
23=7x+9
5) Subtract 9 from both sides:
7x=14
6) Divide both sides by 7:
x=2

- The <em>Distributive</em> property says a(b+c)=ab+ac
