Question

Solve for u.u^2-u-12=0If there is more than one solution, separate them with commas.If there is no solution, click on "No solution."

Answer 1

we have the quadratic equation

`u^2-u-12=0`

we have that

a=1

b=-1

c=-12

Applying the formula to solve a quadratic equation

`u=(-(-1)\pm√(-1^2-4(1)(-12)))/(2(1))`
`u=(1\pm7)/(2)`

The values of u are

u=4 and u=-3

therefore

The answer is

u=-3,4
