Question

3x³-x²-10x.Please help me.I cant solve this question.

Answer 1

HERE'S YOUR ANSWER.....✌️✌️

3x^3 - x^2 -10

= x [ 3x^2 - x - 10 ]

= x [ 3x^2 - ( 6 - 5 )x - 10 ]

= x [ 3x^2 - 6x + 5x - 10 ]

= x [ 3x ( x - 2 ) + 5 ( x - 2 ) ]

= x [ (3x + 5) (x - 2) ]

Answer 2

HEY HERE IS YOUR ANSWER ☺☺☺
${3x}^{3} - {x}^{2} - 10x \\ \\ x( {3x}^{2} - {x} - 10) \\ \\ x( {3x}^{2} - 6x + 5x - 10) \\ \\ x(( {3x}^{2} - 6x) + (5x - 10)) \\ \\ x(3x(x - 2) + 5(x - 2)) \\ \\ x(( x - 2)(3x + 5)) \\ \\ x(x - 2)(3x + 5)$

We have factorised in the format :- ax^2 + bx+ c
HOPE IT HELPS ☺☺
