Question

What is it in standard form

Answer 1

Your answer is correct. A

Answer 2

Standard form is the most simplified expression (or equation, in the case of = 0).

Use the FOIL method.

(2x + 3)(4x² + 10x  + 6)

2x(4x²) = 8x³
2x(10x) = 20x²
2x(6) = 12x
3(4x²) = 12x²
3(10x) = 30x
3(6) = 18

8x³ + 20x² + 12x² + 30x + 12x + 18

Simplify, combine like terms.

8x³ + (20x² + 12x²) + (30x + 12x) + 18

8x³ + 32x² + 42x + 18


8x³ + 32x² + 42x + 18 or A, is your answer
