Find a,b,c 4x^2=5x+9

$4 x^{2} = 5 x + 9$

Step 1

Move all the expressions to the left side of the equation.

Subtract $5 x$ from both sides of the equation.

$4 x^{2} - 5 x = 9$

Subtract $9$ from both sides of the equation.

$4 x^{2} - 5 x - 9 = 0$

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.

$a = 4$ , $b = - 5$ , $c = - 9$
