If 2x^2+2x=12, what is x?
Rainbow [258]

Answer:

x= 2

x= -3

Step-by-step explanation:

<u>Solving as normal quadratic equation:</u>

  • 2x^2+2x=12
  • x^2 +x = 6
  • x^2 + x - 6= 0
  • x = (-1 ± √(1+4*1*6)/2
  • x = ( - 1 ± √25)/2
  • x = (-1 ± 5)/2
  • x= 2
  • x= -3

Can someone explain how to answer this
olya-2409 [2.1K]

Answer:

q= -ck+dp/

-k+d

Step-by-step explanation:

Step 1:

Multiply both sides by p.

dp=ck−kq+pq

Step 2:

Flip the equation.

ck−kq+pq=dp

Step 3:

Add -ck to both sides.

−kq+pq=−ck+dp

Step 4:

Factor out variable q.

q(−k+p)=−ck+dp

Step 5:

Divide both sides by -k+p.

q= -ck+dp/

-k+d
