Question

factorize
x³-5x²-2x+24​

Answer 1

Answer:

Try by keeping 0, 1, 2, 3, 4.. on the place of X so that X^3 - 5X^2 - 2X + 24 = 0

After putting any number on the place of X, if answer comes 0 then that number is the solution of the polynomial.

Step-by-step explanation:

When putting 4 on the place of X :

= X^3 - 5X^2 - 2X + 24

= (4)^3 - 5(4)^2 - 2(4) + 24

= 4×4×4 - 5(4×4) - 2×4 + 24

= 64 - 80 - 8 + 24

Since, 64 - 80 = (-)16 and (-)8 + 24 = (+)16

= -16 + 16 = 0 (zero)

Since, answer came 0 when we put 4 on the place of X then 4 is the solution of this cubic polynomial.

Hope my answer is satisfactory.
