Question

factorise :
x² + 23x + 42​

Answer 1

x² + 23x + 42 = 0

x² + 2x + 21x + 42 = 0

x ( x + 2 ) 21 ( x + 2 ) = 0

( x + 21 ) ( x + 2 ) = 0

x = -2 , -21 ➡ Answer

Answer 2

Answer:

hi friend

your answer is:(x+2)+(x+21)

Step-by-step explanation:

x^2 + 23x +42

by middle term splitting:

x^2+21x+2x +42

x(x+21) +2(x+21)

(x+2)+(x+21)

Hence your answer is:-

(x+2)+(x+21)
