❄❄❄ FACTORISATION ❄❄❄
➡ The process of finding two or more expressions whose product is the given expression is called factorisation.
➡ Example 1 :- 4x²-25 = (2x+5) (2x-5)
➡ Example 2 :- 24x³-32x² = 8x²(3x-4)
==================================
LIKEWISE, y³-2y²-29y-42
= y³+2y²-4y²-8y-21y-42
= y²(y+2)-4y(y+2)-21(y+2)
= (y+2) (y²-4y-21)
= (y+2) (y-7) (y+3) [REQUIRED ANSWER]
