Problem 8. Solve the quadratic equation. x 2 + 3 x − 7 0 = 0. \displaystyle x^2+3x-70=0 x2 +3x−70 = 0. In the answer box, write the roots separated by a comma. Solution: The discriminant is 3 2 + 4 ⋅ 7 0 = 2 8 9 = 1 7 2 \displaystyle 3^2+4\cdot 70=289=17^2 3 2 + 4 ⋅ 70 = 289 = 1 7 2.

The quadratic formula to find the roots, x = [-b ± √ (b 2 -4ac)] / 2a Now, let us find the roots of the equation above. x 2 +2x-6 = 0 Here, a = 1, b=2 and c= -6. Substituting these values in the formula, x = [-2 ± √ (4 – (4*1*-6))] / 2*1 → x = [-2 ± √ (4+24)] / 2 → x = [-2 ± √28] / 2
