Answer» Answer: Hope it will help you mark me as brainleast or thanks me please.. Step-by-step explanation: To CHECK that x−2 is the factor of x 3 −2x 2 −5x+4 Then the value of x−2=0, so x=2. So, PUT x=2 in expression, we get f(x)=x 3 −2x 2 −5x+4 f(2)=(2) 3 −2(2) 2 −5(2)+4 ⇒f(2)=8−2×4−5×2+4 ⇒f(2)=8−8−10+4 ⇒f(2)=−6 Remainder is not zero when x−2 DIVIDED polynomial x 3 −2x 2 −5x+4. Thus x−2 is not a factor of polynomial x 3 −2x 2 −5x+4. MARK ME AS BRAIN LEAST

Answer:

Hope it will help you mark me as brainleast or thanks me please..

Step-by-step explanation:

To CHECK that x−2 is the factor of x 3 −2x 2 −5x+4

Then the value of x−2=0, so x=2.

So, PUT x=2 in expression, we get

f(x)=x 3 −2x 2 −5x+4

f(2)=(2) 3 −2(2) 2 −5(2)+4

⇒f(2)=8−2×4−5×2+4

⇒f(2)=8−8−10+4

⇒f(2)=−6

Remainder is not zero when x−2 DIVIDED polynomial x 3 −2x 2 −5x+4.

Thus x−2 is not a factor of polynomial x

3 −2x 2 −5x+4.
