Question

(x+4)(x²-4x+16)-(x+3)(x²-3x+9) can you solve this question for me plzz....​

Answer 1

Answer:

37

Step-by-step explanation:

(x+4)(x²-4x+16) = (x+4){ (x²) - (4)(x) +(4)² } = x³+4³

also

(x+3)(x²-3x+9) = (x+3){ (x²) -(3)(x) + (3)² } = x³+3³

therefore

(x+4)(x²-4x+16)-(x+3)(x²-3x+9) = (x³+4³) -(x³+3³)

= x³ + 4³ - x³ - 3³

= 4³-3³

= 64-27

= 37
