Megan's solution isn't correct.
The first mistake: she subtracted 5x from the right-hand side of the equation, but added 5x to the left-hand side.
The second mistake: she divided the right-hand side of the equation by 11, but didn't divide the left-hand side.
The correct solution:
Step-by-step explanation:
So 4x2+9 has no linear factors with Real coefficients. It is possible to factor it with Complex coefficients.
The ANSWERRRRRRR would be 32
-12 + 3x + 2 = 5x - 10 - 8x
-10 + 3x = -3x -10
-10 + 6x = -10
6x = 0
x = 0
