Solve the following system of equations. (Hint: Use the quadratic formula.) f(x) = 2x² 3x g(x)=-3x² + 20 (0.-10) and (1, 17) (-2

jasenka [17]

The solution of the system of equation is the intersection point of the two quadratic equations, so we need to equate both equations, that is,

$2x^2-3x-10=-3x^2+20$

So, by moving the term -3x^3+20 to the left hand side, we have

$5x^2-3x-30=0$

Then, in order to solve this equation, we can apply the quadratic formula

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

In our case, a=5, b=-3 and c=-30. So we get

$x=\frac{3\pm\sqrt{(-3)^2-4(5)(-30)}}{2(5)}$

which gives

$\begin{gathered} x=2.76779 \\ and \\ x=-2.16779 \end{gathered}$

By substituting these points into one of the functions, we have

$f(2.76779)=-2.982$

and

$f(-2.16779)=5.902$

Then, by rounding these numbers to the nearest tenth, we have the following points:

$\begin{gathered} (2.8,-3.0) \\ and \\ (-2.2,5.9) \end{gathered}$

Therefore, the answer is the last option
