Question

Simplify(x+5)(x+6)(x+7)

Answer 1

Step-by-step explanation:

(x+5)(x+6)(x+7)

= [(x+5)(x+6)] (x+7)

here , take x common

= [x(5+6)] (x+7)

=[x(11)] (x+7)

= (11x)(x+7) = 11x*x +11x*7

= 11x^2 + 77x

Answer 2

Step-by-step explanation:

first take (x +5)&(x+6)

=>x²+6x+5x+30

=>x²+11x+30

now multiply it with (x+7)

x³+7x²+11x²+77x+30x+210

this will give us the answer

=> x³+18x²+107x+210
