Solve using the quadratic formula x2 - 6x - 40=0 Question options: x = 10 or x = -4 x = 4 or x = -10 x = -7 or x = 7 x = -4 - √7

Crazy boy [7]

Answer:

$x=-10$ or $x=4$

Step-by-step explanation:

$ax^2+bx+c=0$

$x^2-6x-40=0$

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

$x=\frac{-6\pm\sqrt{6^2-4(1)(-40)}}{2(1)}$

$x=\frac{-6\pm\sqrt{36+160}}{2}$

$x=\frac{-6\pm\sqrt{196}}{2}$

$x=\frac{-6\pm14}{2}$

$x=-3\pm7$

$x=-10$ or $x=4$
