Write in Standard Form 4x+5x^2=8x-7

$4 x + 5 x^{2} = 8 x - 7$

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

Subtract $8 x$ from both sides of the equation.

$4 x + 5 x^{2} - 8 x = - 7$

Add $7$ to both sides of the equation.

$4 x + 5 x^{2} - 8 x + 7 = 0$

Subtract $8 x$ from $4 x$ .

$5 x^{2} - 4 x + 7 = 0$

To write a polynomial in standard form, simplify and then arrange the terms in descending order.

$a x^{2} + b x + c = 0$

The standard form is $5 x^{2} - 4 x + 7$ .

$5 x^{2} - 4 x + 7 = 0$
