If (x - 1) is a factor of x3 + x2 + kx - 2, find the value of k.

If (x-1) is a factor of the expression, that means that x=1 using the zero product property. A zero to this function is (1,0). Substitute this value into the equation to find the value of x.

y=3x+2x+1k-2 where (1,0) is a zero.

0=3+2+k-2

0=3+k

k=-3

step-by-step explanation:

the triangles are similar. therefore the corresponding sides are in proportion:

              cross multiply

            divide both sides by 32

the answer would be 0.54
