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
hope this helps
