Answer 1

Answer:

10x⁴-37x³+53x²+2x-12

Step-by-step explanation:

(2x²-5x+3)(5x²-6x-4)

→2x²(5x²-6x-4)-5x(5x²-6x-4)+3(5x²-6x

→10x⁴-q12x³-8x²-25x³+30x²+20x+75x²-18x-12

→10⁴-37x³+53x²+2x-12

→10x⁴-37x³+53x²+2x-12....…......

Answer 2

Answer:

Hope it helps you !! :)

Step-by-step explanation:

$=(2x^2-5x+3)(5x^2-6x-4)\\\\\\=2x^2(5x^2-6x-4)-5x(5x^2-6x-4)+3(5x^2-6x-4)\\\\\\=(10x^4-12x^3-8x^2)-(25x^3-30x^2-20x)+(15x^2-18x-12)\\\\\\=10x^4-12x^3-8x^2-25x^3+30x^2+20x+15x^2-18x-12\\\\\\=10x^4-12x^3-25x^3-8x^2+30x^2+15x^2+20x-18x-12\\\\\\=10x^4-37x^3+37x^2+35x-12$
