Question

Solve please 4x^2-24x

Answer 1

We solve as follows:

`x=\frac{-(-24)\pm\sqrt[]{(-24)^2-4(4)(0)}}{2(4)}`

Then:

`\begin{gathered} x=0 \\ x=6 \end{gathered}`

As we can see the function:

`4x^2-24x`

Is of the form:

`ax^2+bx+c`

Where a = 4, b = -24 & c = 0

Since it follows that form, we can solve it using the quadratic function:

`x=\frac{-b\pm\sqrt[]{b^2-4ac}}{2a}`

When we solve it gives us that x = 0 and x = 6 when we equal to 0.
