Question

multiply (2x^2 +3x = 5 )&( 3x^2 - 5x + 4) ​

Answer 1

Answer:

6x^4 - x^3 - 22x^2 + 37x + 20

Step-by-step explanation:

(2x^2 + 3x -5)(3x^2 - 5x + 4)

2x^2(3x^2 - 5x + 4) + 3x(3x^2 - 5x + 4) -5(3x^2 - 5x - 4)

(6x^4 - 10x^3 + 8x^2) + (9x^3 - 15x^2 + 12x) + (- 15x^2 + 25x + 20)

6x^4 - 10x^3 + 8x^2 + 9x^3 - 15x^2 + 12x - 15x^2 + 25x + 20

6x^4 - 10x^3 + 9x^3 + 8x^2 - 15x^2 - 15x^2 + 12x + 25x + 20

6x^4 - x^3 - 22x^2 + 37x + 20
