Find a,b,c 5x^2-8x-5=15

$5 x^{2} - 8 x - 5 = 15$

Step 1

Move all terms to the left side of the equation and simplify.

Subtract $15$ from both sides of the equation.

$5 x^{2} - 8 x - 5 - 15 = 0$

Subtract $15$ from $- 5$ .

$5 x^{2} - 8 x - 20 = 0$

Step 2

Once the quadratic is in standard form, the values of $a$ , $b$ , and $c$ can be found.

$a x^{2} + b x + c$

Step 3

Use the standard form of the equation to find $a$ , $b$ , and $c$ for this quadratic.

$a = 5$ , $b = - 8$ , $c = - 20$
