Answer :
To find the remainder when [tex]\(x^2 - x + 3\)[/tex] is divided by [tex]\(x - c\)[/tex], with [tex]\(c = -2\)[/tex], we can use the Remainder Theorem. The Remainder Theorem states that if you divide a polynomial [tex]\(f(x)\)[/tex] by [tex]\(x - c\)[/tex], the remainder is [tex]\(f(c)\)[/tex].
Let's follow the steps:
1. Identify the Polynomial and the Value of [tex]\(c\)[/tex]:
- Polynomial: [tex]\(f(x) = x^2 - x + 3\)[/tex]
- [tex]\(c = -2\)[/tex]
2. Substitute [tex]\(c = -2\)[/tex] into the Polynomial:
- Calculate [tex]\(f(-2)\)[/tex]:
[tex]\[
f(-2) = (-2)^2 - (-2) + 3
\][/tex]
3. Evaluate the Expression:
- [tex]\((-2)^2 = 4\)[/tex]
- [tex]\(-(-2) = 2\)[/tex]
- Sum up the values:
[tex]\[
f(-2) = 4 + 2 + 3 = 9
\][/tex]
4. Determine the Remainder:
- The remainder when [tex]\(x^2 - x + 3\)[/tex] is divided by [tex]\(x + 2\)[/tex] is 9.
Thus, the remainder is 9.
