Question

factorizar 2x4+4x2 = x²-4= x⁴-16 = x²-x-6= x²-2x-3= 2x³-50x= 2x⁵-32x= x²-6x+9 = x²-20x+100=​

Answer 1

1) 2x4+4x2 factor comun 2x^2

2x^2( x^2 +2)

x²-4= (x+2)(x-2)

x⁴-16 =(x^2-4) (x^2 +4)

x²-x-6= (x-3) (x+2)

x²-2x-3= (x-3) (x+1)

2x³-50x= 2x (x^3 -25)

2x⁵-32x= 2x( x^5-16)

x²-6x+9 = (x-3) (x-3)

x²-20x+100= (x-10) (×-10)
