Question

Find the integral zeros of following polynomials
1. (X-3)(7-x)(2x+1)

Answer 1

Answer:

3 and 7 are the integral zeros

Step-by-step explanation:

3 and 7 are tge only intehral roots

it also has a ratuonal root which is not integral which is -1/2

Answer 2

Answer:

25x-3x^2

Step-by-step explanation:

x×7-x×x-3×7-3×x

7x-x^2-18x

7x-18x-x^2

(-25x-x^2)(2x+1)

-25x×2x-25x×1-x^2×2x-x^2×1

50x-25x-2x^2-x^2

25x-3x^2
