(x-2) (x+9)= 4x solve and check solution

x = -6 and x=3

Step-by-step explanation:

We have been given the equation to solve

Let us simplify the left hand side of the equation using FOIL (first outer in last).

Now, let us find the factors using AC method.

Middle term 3x can be written as 6x - 3x

Now, let us check the solution by plugging values in the original equation

For x= -6

Thus, x=-6 is a solution.

For x= 3

Thus, x=3 is a solution.

Therefore, the solutions are x = -6 and x=3
