Question

factorise the following by splitting the middle term: (i) x²-23x+120​

Answer 1

Answer:

x^2-15x-8x+120

Step-by-step explanation:

x(x-15)-8(x-15)

(x-8)(x-15)

Answer 2

Answer:

(x-8) (x-15)

Step-by-step explanation:

${x}^{2} - 23x + 120$

$= {x}^{2} - 8x - 15x + 120$

[By middle term factorization]

$= x(x - 8) - 15(x - 8)$

= (x-8) (x-15) (Ans)
