Question

 {x}^{2}  +  - 4x -  24

solution

We have to factorise it by middle term splitting

so

 {x}^{2}   - 4x - 24 \\  \\  {x}^{2}   + 4x  - 8x - 24 \\  \\  \\ x (x  + 4) - 8(x + 4) \\  \\  \\  \\  \\ (x + 4)(x - 8)

so here is your answer

The question given is wrong

I think you meant

x²-4x-21

Answer:

(m-7)(m+3)

Step-by-step explanation:

m^{2} -4m-21

m^{2} +3m-7m-21

m(m+3)-7(m+3)

(m-7)(m+3)

∴ The factors are (m-7)(m+3)
