Rewrite the equation 8x + 6x^2 -7=x^2 in standard form and identify a, b, and c.

Vladimir79 [104]

Answer:

$5x^2+8x-7=0\\a=5\\b=8\\c=-7$

Step-by-step explanation:

The standard form of a quadratic is $ax^2+bx+c=0$ . You need to subtract the x^2 from the right to set the quadratic equal to 0. Then a,b, and c are equal to the values of the coefficients in front of the terms.

If this helped, a brainliest would be greatly appreciated!
