Question

Necesito ayuda en el B, gracias.

Answer 1

4(4x²-2)² -5(x²-2x)(x²+2x) + 3(2x+1)(3-2x)

4[(2)(x²-1)]² -5[(x⁴-4x²)] -3(2x+1)(2x-3)

(4)(2)²(x²-1)² -5x⁴+20x²-3(4x²-4x-3)

16(x⁴-2x²+1) -5x⁴+20x²-12x²+12x+9

16x⁴-32x²+16-5x⁴+20x²-12x²+12x+9

11x⁴-24x²+12x+25

Answer 2

4(16x^4-16x^2-4)-5(x^4+2x^3-2x^3-4x^2)+3(6x-4x+3-2x)
64x^4-64x^2-16-5x^4-10x^3+10x^3-20x^2+18x-12x+9-6x
61x^4-80x^2+12x-7
