Solve this equation for x: 2x^2 + 12x - 7 = 0 What is the first step to solve this equation?

-combine like terms

-factor the trinomial

-isolate the constant term by adding 7 to both sides

x=0.5355 or x=-6.5355

First step is to: Isolate the constant term by adding 7 to both sides

Step-by-step explanation:

We want to solve this equation:

On observation, the trinomial is not factorizable so we use the Completing the square method.

Step 1: Isolate the constant term by adding 7 to both sides

Step 2: Divide the equation all through by the coefficient of which is 2.

Step 3: Divide the coefficient of x by 2, square it and add it to both sides.

Coefficient of x=6

Divided by 2=3

Square of 3=

Therefore, we have:

Step 4: Write the Left Hand side in the form

Step 5: Take the square root of both sides and solve for x
