Expand and simplify (X+2)(x+3)(x+6)

x³ + 11x² + 36x + 36

Step-by-step explanation:

(x+2)(x+3)

x² + 3x + 2x + 6

x² + 5x + 6

(x² + 5x + 6)(x+6)

x³ + 6x² + 5x² + 30x + 6x + 36

x³ + 5x² + 6x² + 30x + 6x + 36

x³ + 11x² + 36x + 36

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!
