Question

3x^2+24x-9 factorise

Answer 1

1. 3x^2+24x-9
= 3×x×x+3×8×x-3×3
= 3(1x^2+8x-3)

Answer 2

$\underline{\bold{Factorization}}$

$\implies\bold{3{x}^{2} + 24x -9}$

Let factorise each and every term ,

$\implies\bold{3\times x\times x + 2\times 2\times 2\times 3 - 3\times 3}$

Take three as common ,

$\implies\bold{3({x}^{2} + 8x -3)}$

therefore, the final answer is :

${3({x}^{2} + 8x -3)}$
