-5 and -2 The quadratic equation is: __=0 Thank you.
a leading coefficient x1 and x2 roots In this case : x 1 = - 5 x 2 = - a [ x - ( - 5 ) ] * [ x - ( - 2 ) ] = a ( x + 5 ) * ( x + 2 ) = a ( x * x + x * 5 + 2 * x + 2 * 5 ) = a ( x ^ 2 + 5 x + 2 x + 10 ) = a ( x ^ 2 + 7 x + 10 ) a ( x ^ 2 + 7 x + 10 ) = 0 Divide both sides by a x ^ 2 + 7 x + 10 = 0 / a x ^ 2 + 7 x + 10 = 0
