Question

(x + 2)(x + 3)(x + 4)(x + 5) – 48​

Answer 1

Answer:

4x - 34

Step-by-step explanation:

(x + 2)(x + 3)(x + 4)(x + 5) – 48

= (x + x + x + x) + (2+3+4+5) -48

= 4x + 14 - 48

= 4x - 34

Answer 2

Answer:

Step-by-step explanation:

(x+2)(x+3)(x+4)(x+5)-48

=(x+2)(x+5)(x+3)(x+4)-48

=(x2+2x+5x+10)(x2+3x+4x+12)-48

=(x2+7x+10)(x2+7x+12)-48

=(a+10)(a+12)-48 [a=x2+7x]

=a2+10a+12a+120–48

=a2+22a+120–48

=a2+22a+72

=a2+18a+4a+72

=a(a+18)+4(a+18)

=(a+18)(a+4)

=(x2+7x+18)(x2+7x+4)
