Answer:-5

Step-by-step explanation:

=>x-1 is a factor

Another quadratic factor is

x^2-3x+10.

By midterm factorization

=(x-2)(x+5)

=>x=2,-5

if 1 and -2 are two zeros of the polynomial (x cube -4x square -7x +10), find its third zero.if 1 and -2 are two zeros of the polynomial (x cube -4x square -7x +10), find its third zero.if 1 and -2 are two zeros of the polynomial (x cube -4x square -7x +10), find its third zero.
