Find the roots of the quadratic polynomail 5x^2-9x-3

please show steps.

The quadratic formula:

x=(-b (+ or -) sqrt((b^2)-4ac))/(2a)

so

(9(+ or -) sqrt(81+60))/(10)=0.9 (+ or -) 1.1874

So, the two roots are -0.2874 and 2.0874.

x = -0.29 or x = 2.09

you can solve this with the quadratic equation or completing of squares

get detailed answers @

lets see if itll factor nicely.

81 - (4)(5)(-3)

141

Thats not a perfect square so to find roots use quadratic formula.
(-b±√(b^2 - 4ac)) / 2a

Use the quadratic formula. If you actually need more help that this, then I weep for the future.
