A quadratic equation 'ax^2+bx + c' can be factored into an equivalent equation:

ax^2+bx + c = a(x - x1)(x - x2)

where 'x1' and 'x2' are the solutions for 'x'.

So, if you solve the equation 'x^2+3x-8=0' using the 'Solve' tab you will find the solutions x1 and x2:

Npw, lets plugin the values 'x1' and 'x2' into: 'x^2 + 3x - 9 = (x - x1)(x - x2)' and we get:
