Question

Use the factor theorem to determine whether ji bracket X bracket is a factor of X in each of the following case
P(x) =2x2 +x2 -2x -1; g(x) = x+ 1

Answer 1

Answer:

X=-1

PUT X IN p(x)

${2 \times ( - 1)}^{2} - {( - 1)}^{2} - 2 \times 1 - 1$

=(-2)-1-2-1

=-2-1-2-1

=-6

HOPE IT HELPS

Answer 2

• Answer:

g(x)=x+1=-1

• put the value -1 p(x). p(-1)=4×-1+2×-1-2×-1-1. =-4-2+2-1 = -6+1 =-5. Answer is -5
