To solve, you must make one side of the equation equal to zero. We can do this by subtracting 3x on both sides of the equation.
<span>x^2 + 7x = 3x
</span> - 3x -3x
x^2 + 4x = 0.
Then we substitute the equation into the quadratic equation.
Where a = 1 b = 4 and c = 0
We first solve whats inside the square root.
Now we solve for -4 and 4.
Then divide both answer by 2
The division of any by zero is zero
So the answer are x = -4 and x = 0
