Won't factor, use quadratic formula
anonymous

not to butt in but you can find the sum of the roots and the produce of the roots without finding the roots

Alright then, the floor is yours lol

you can also prove those formulas using the quadratic formula, but sum of roots of a quadratic \[ax^2+bx+c=0\] \[r_1+r_2=-\frac{b}{a}\] produce is \[r_1r_2=\frac{c}{a}\]

The answer is 289/49. Could you please show me the steps?

product of the roots, according to satellite's formula is -13/7
anonymous
  • anonymous
sum is -4/7

\[(-\frac{13}{7}-\frac{4}{7})^2=(-\frac{17}{7})^2=\frac{289}{49}\]
