The x intercepts occur where x = 8 and x= -3
What is Quadratic equation?
A quadratic equation is an algebraic equation of the second degree in x. The quadratic equation in its standard form is [tex]ax^{2}+bx+c=0[/tex].
What is x intercept?
The x-intercept is where a line crosses the x-axis
Given,
[tex]-x^{2} +5x+24=0[/tex]
Factor the expression,
[tex]-x^{2} +5x+24=0\\-(x^{2} -5x-24)=0\\x^{2} -5x-24=0\\(x-8)(x+3)=0\\[/tex]
Therefore,
x= 8 and x = -3
Hence, the x intercepts occurs where x= 8 and x= -3
