1.
2x (4x² -3x +8) - (3x+4)
8x³ - 6x² +16x -3x -4
8x³ -6x² +13x -4
2.
3x(2x²-7)+7x(x²+4)
6x³ -21x +7x³ +28x
13x³ +7x
3.
2x² (-4x^4 -12x² - x +17)
-8x^6 - 24x^4 - 2x³ + 34x²
Flip the second fraction and change the fraction into multiplication
Also, change 2 1/2 into a improper fraction
2 1/2 = 5/2
(5/2)/(5/8) becomes 5/2 x 8/5
Multiply across
5 x 8 = 40
------- -----
2 x 5 = 10
Simplify 40/10
40/10 = 4
4 is your answer
