Rewrite the polynomial in the form ax^2 + bx + C and then identify the values of a, b, and c.

sergejj [24]

Answer:

$a = 5\\\\b = -1\\\\c=1$

Step-by-step explanation:

Given

$-x+5x^2+1$

Required

Rewrite and identify a, b and c

The required form is:

$ax^2 + bx + c$

Equate both expressions

$ax^2 + bx + c = -x+5x^2+1$

Rewrite as:

$ax^2 + bx + c = 5x^2-x+1$

Compare the expressions on either sides

$a = 5\\\\b = -1\\\\c=1$
