Question

if 1 and _2 or 2 zeros of the polynomial x cube minus 4 x square - 7 x + 10 find its third zero

Answer 1

Since x =1 and x= -2, (x-1) and (x+2) are factors. Multiply them and you'll get a combined factor. Divide the polynomial by the factor and you'll get your answer from the quotient.
Hope this helps :)
