A quadratic equation in the form of ax²+bx+c. The zeroes of the polynomial are -2.4 and -7.5.
What is a quadratic equation?
A quadratic equation is an equation whose leading coefficient is of second degree also the equation has only one unknown while it has 3 unknown numbers. It is written in the form of ax²+bx+c. The Root of the quadratic equation are given as,
[tex]x = \dfrac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]
The zeroes of the polynomial are:
f(x)=x² + 9.9x + 18
0 = x² + 9.9x + 18
[tex]x= \dfrac{-9.9\pm \sqrt{(9.9)^2-4(1)(18)}}{2(1)}\\\\[/tex]
x = -2.4, -7.5
Hence, the zeroes of the polynomial are -2.4 and -7.5.
