# Sum of The Roots of The Equation ax² + bx² + c =0

If the sum of the roots of the equation ax² + bx² + c =0 is equal to the sum of their square, then

- a
^{2}+ b^{2}= c^{2} - a
^{2}+ b^{2}= a + b - ab + b
^{2}= 2ac - ab – b
^{2}= 2ac

If the sum of the roots of the equation ax² + bx² + c =0 is equal to the sum of their square, then

- a
