Question

2x^2-3x-65=0

Answer 1

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

This is the formula to find the roots of the equation.

Answer 2

X=13/2

Answer 3

I have no idea what I'm doing

Answer 4

Quadratics equations are of the form ax^2+bx+c

The equation which you posted is also of this form. Where a=2; b=-3;c=-65

Now, plug this value into the equation posted above and you will find the value of x for which the equation is ZERO. In other terms you will find the roots of the equation.

Did you understand this.? :)
