Answer 1

solution 26

Given that

(x+1)and(x+2) are two factors of cubic polynomial: x³+3x²-2px+q

Since it is a cubic Polynomial; let us assume its third factor be (x+k)

Hence we should have

(x+1)(x+2)(x+k)= x³+3x²-2px+q

On multiplying the factors on LHS and arranging the term of like power; we get

x³+x²(k+3)+x(3k+2)+2k= x³+3x²-2px+q
