In this case, we'll have to carry out several steps to find the solution.
Step 01:
Data
roots:
x1 = 10 ===> ( x - 10)
x2 = - 7 ===> (x + 7)
Step 02:
By multiplying the roots we can obtain the quadratic equation.
(x - 10) * (x + 7) = 0
x² + 7x - 10x - 70 = 0
x² - 3x - 70 = 0
The answer is:
x² - 3x - 70 = 0
