Select the simplification that accurately explains the following statement. 37 = 73
OA (73) = 73.73.73 = 7. (1++ 3) = 7.5 = 7 -1 = 7
OB (73) = 73.73.75 = 73-}.} = 7: = 71 = 7
oc (72) = 75.78.75 = 7.74= 3-5-7 = 1.7 = 7
D. (-) = 77.73.73 = 7++ = 78 = 71 = 7

- 2 + 10x³ - 21x² + 19x - 4

step-by-step explanation:

each term in the second factor is multiplied by each term in the first factor

x²(- 2x² + 4x - 1) - 3x(- 2x² + 4x - 1) + 4(- 2x² + 4x - 1) ← distribute

= - 2 + 4x³ - x² + 6x³ - 12x² + 3x -8x² + 16x - 4

collect like terms

= - 2 + 10x³ - 21x² + 19x - 4 ← in standard form
