8) <br> Solve using the Quadratic Formula.<br><br> x2 + 3x - 5 = 0
maks197457 [2]

Step-by-step explanation:

x^{2} + 3x - 5

For any quadratic equation ax^{2} + bx + c = 0, the quadratic formula is as follows:

\frac{-b \pm \sqrt{b^{2} - 4ac}}{2a}

From the given quadratic equation, we know that a = 1, b = 3 and c = -5. Plugging in these values into the quadratic formula gives us the following:

\frac{-(-3) \pm \sqrt{(3)^{2} - 4(1)(-5)}}{2(1)}

\frac{3 \pm \sqrt{9 + 20}}{2}

\frac{3 \pm \sqrt{29}}{2}
