Question

4Which of the following is a solution to the equation2x2 + 4x = 3 + 3x? ?A) -1B)0.C)3D)6

Answer 1

We have the following:

`2x^2+4x=3+3x^2`

solving for x:

`\begin{gathered} 2x^2+4x=3+3x^2 \\ 3x^2-2x^2-4x+3=0 \\ x^2-4x+3=0 \\ (x-1)(x-3=0 \\ x-1=0\rightarrow x=1 \\ x-3=0\rightarrow x=3 \end{gathered}`

Therefore, the answer is C) 3
