Question

multiply 3 x³-7 x +8-2x² by 4x²+6​

Answer 1

Step-by-step explanation:

= 4x² ( 3 x³-7 x +8-2x² )+6( 3 x³-7 x +8-2x² )

= 12x²x³ - 28x³+32x²-8x^4 + 18x³-42 x +48-12x²

= 12x²x³-8x^4 -10x³-20x²-42x+48

Answer 2

Step-by-step explanation:

(3 x³-7 x +8-2x²)*(4x²+6)

4x²(3 x³-7 x +8-2x²)+6(3 x³-7 x +8-2x²)

12x⁵-28x³+32x²-8x⁴+18x³-42x+48-12x²

12x⁵-8x⁴-28x³+18x³+32x²-12x²-42x+48

12x⁵-8x⁴-10x³+20x²-42x+48
