Ans:- x²-x -110
= x²-11x + 10x - 110
= x(x -11) + 10(x - 11)
= (x-11)(x+10)
2. 8x³+27y³+z³-18xyz
we know that (a³+b³+c³-3abc) = (a+b+c)(a²+b²+c² - ab - bc - ca).
Now,
= 8x³+27y³+z³-18xyz
= (2x)³+(3y)³+(z)³ - 3×(2x)×(3y)×(z)
= (2x + 3y + z)(4x²+9y²+z²- 36xy - 9yz - 4xz)
here is your answer
hope it will help you
