Question

Factorise: x² + 30x + 81 using middle term splitting method​

Answer 1

Step-by-step explanation:

${x}^{2} + 30x + 81 = {x}^{2} + 27x + 3x + 81$

$x(x + 27) + 3(x + 27)$

$(x + 3)(x + 27)$

Answer 2

Answer:

x² + 30x +81 = (x+27)(x+3)

Step-by-step explanation:

x² + 30x + 81

= x² + 27x + 3x + 81

= x( x + 27) + 3(x + 27)

= (x +3)(x + 27)
