Factorise the polynomial {eq}f(x) = 2x^3 +15x^2+3x-72 {/eq}, if {eq}f(-3) = 0 {/eq}. Factorization of polynomial: There are several ways to factorize a polynomial. For the given polynomial, since we are provided with the information that {eq}f(-3)=0 {/eq}, ...
such that a + b =5 and ab = 6. on solving this we obtain, a = 3 and b = 2 thus, the above expression can be written as: x 2 + 3x + 2x + 6 = x(x + 3) + 2(x + 3) = (x + 3)(x + 2) thus, x+3 and x+2 are the factors of the polynomial x 2 + 5x + ...
