Question

Find all the connam zero ploynomial x2+5x2 -9X-45 and x3+8x2+15x
answer

Answer 1

$\huge \bold \red{answer}$

Let P(x) = x3 + 5x2 - 9x - 45 and Q(x) = x3 + 8x2 + 15x.

Let P(x) = x3 + 5x2 - 9x - 45 = x2(x + 5) - 9 (x+5)

= (x+5) (x2 - 9)

= (x+5) (x+3) (x-3)

Q(x) = x3 + 8x2 + 15x = x(x2 + 8x + 15)

= x (x+5) (x+3)

∴ The common zeroes of the polynomials are (x+5) and (x+3).

polynomials are (x+5) and (x+3).
