Question

if 1 and -2 are two zeros of the polynomial x^3-4x^2-7x+10,find its third zeros

Answer 1

Hey!!!!

let p(x) = x³ - 4x² - 7x + 10

=> zeros = 1 and -2

=> factors = (x - 1)(x + 2)
=> factor = x² + x - 2

By Long Division Method,

For Division refer to the attachment

Thus the third zero is 5
