Question

Factorise by splitting the middle term​

Answer 1

3 x square + 8 x + 5 3 square + 5 x + 3 x + 5

(3 x + 5) + 1 (3 x + 5)

give us answer x + 1 and 3 x + 5

Answer 2

Answer:

$(x - 7)(x + 6)$

Step-by-step explanation:

1. ${x}^{2} - x - 42$

Splitting the middle term into -7 and 6

${x}^{2} - 7x + 6x - 42$

$x(x - 7) + 6(x - 7)$

$(x - 7)( x + 6)$
