Since we are only asked to put the quadratic equation in standard form, then we will only focus on that particular condition.
Given:
x^2 + 7x = 8
In order to change the given quadratic equation to standard form, we must have first all the value on one side. Hence, we must transpose 8 on the other side of the equation. We must take note that in transposing a number, the sign changes, therefore 8 will become -8.
x^2 + 7x -8 = 0
