Answer:

I can't solve and show it but only tell a method to do it!

So find the zero of the given factor:

i.e.

$(x + 1) \\ x = - 1$

Now put its value (-1) in the polynomial

${x}^{3} - 13 {x}^{2} + 32x - 20$

Now if the answer comes zero it is a factor.

You'll get your answer!

Answer:

(D) 2 x 10²

Step-by-step explanation:

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.
