Question

What is the answer of(X+8)(x+4)

Answer 1

x² + 12x + 4

Explanation:

(x + 8)(x + 4)

x(x + 4) + 8(x + 4)

x² + 4x + 8x + 4

x² + 12x + 4

Answer 2

Answer: x² + 12x + 32

Explanation:

Use the FOIL technique:

(FOIL = first, outside, inside, last)

Multiply:

`\sf{x*x+x*4+8*x+8*4}`

`\sf{x^2+4x+8x+32}`

`\sf{x^2+12x+32}`

Therefore, the answer is x^2 + 12x + 32.
