Question

A) (x+1) • (x+2) • (x+3)упростить​

Answer 1

можно ,конечно просто раскрыть скобки, а можно так:

(х+2)=у

у*(у+1)(у-1)=y*(y^2-1)=y^3-y

(x+2)^3-x-2

Вот только годится ли такое "упрощение" ?

А раскрыть скобки  теперь проще:

x^3+3x^2*2+3x*4+8-x-2=x^3+6x^2+11x+6

Answer 2

To simplify the expression (x+1) • (x+2) • (x+3), you can use the distributive property of multiplication over addition. Here's the step-by-step simplification:

1. Start by multiplying the first two terms: (x + 1) • (x + 2) = x^2 + 2x + x + 2 = x^2 + 3x + 2

2. Now, multiply the result from step 1 with the third term: (x^2 + 3x + 2) • (x + 3) = x^2•x + 3x^2 + 2•x + 3•3x + 2•3 = x^3 + 3x^2 + 2x + 9x + 6

3. Finally, combine like terms: x^3 + 3x^2 + 2x + 9x + 6 = x^3 + 3x^2 + 11x + 6

So, the simplified form of the expression is: x^3 + 3x^2 + 11x + 6
