Which of the following polynomials has a remainder of 24 when divided by x+2?

Bad White [126]

Option C is the correct choice $-2x^4+4x^2+3x-2$ ,

Remainder of a polynomial by substitution

For a polynomial f(x) to give a remainder of 24 when divided by x + 2:

f(-2) = 24

By testing, substitute x = -2 into the equation $-2x^4+4x^2+3x-2$

$f(x) = -2x^3+4x^2+3x-2\\\\f(-2)=-2(-2)^3+4(-2)^2+3(-2)-2\\\\f(-2)=-2(-8)+4(4)-6-2\\\\f(-2)=16+16-8\\\\f(-2)=32-8\\\\f(-2)=24$

Since f(-2) = 24 when x = -2 is substituted into $-2x^4+4x^2+3x-2$ , then $-2x^4+4x^2+3x-2$ has a remainder of 24 when divided by x+2

If f(x) = 2x² +5√(x-2), complete the following statement:<br> f(3) =

Musya8 [376]

We just replace the "x" with the starting number (in this case "3").

$f(3) \: = \: 2(3) ^{2} \: + \: 5 \sqrt{3 \: - \: 2}$

$f(3) \: = \: 2 \: \times \: 9 \: + \: 5 \sqrt{1}$

$f(3) \: = \: 18 \: + \: 5 \: \times \: 1$

$f(3) \: = \: 18 \: + \: 5$

$f(3) \: = \: \boxed{ \bold{23}}$
