Question

factorisex^3+2x^2-5x-6 and hence slove x^3+2x^2-5x-6=0​

Answer 1

Answer:

check the answer I have send

Step-by-step explanation:

first you check the, factors of '6'

that is +1,-1,+2,-2,+3,-3,+6,-6

then we have to arrange this in such a way that the addition of three digit =2 and multiplication of same digit =6

that is...... +1-2+3=2 and 1*2*3=6

so that factor of x^3 +2x^2-5x-6 = (x+1)(x-2)(x+3)
