Question

check whether, (x-2) is a factor of
the polynomial ( 3 – x²-4) by using
factox Shemen​

Answer 1

Explanation :Factor theorem

If x - a is a factor of a function f ( x )

then x = a is a solution or zero of the function given .

Checking whether it holds true for f ( x )x - 2 = 0= > x = 2

Put this in f ( x )x³ - x² - 4 =

> 2³ - 2² - 4= >

8 - 4 - 4= >

8 - 8= > 0

Hence f ( x ) = 0

This proves that x - 2 is a factor !Hope it helps !______________________________________________________
