Question

resuelve los siguientes productos notables:
a) (2x+3)³
b) (2x-4)³ ​

Answer 1

a)=(2x+3)*(2x+3)*(2x+3)

=(2x+3)(4x^2+12x+9)

=(2x)(4x2)+(2x)(12x)+(2x)(9)+(3)(4x^2)+(3)(12x)+(3)(9)

=8x^3+24x^2+18x+12x2+36x+27

=8x^3+36x^2+54x+27

b.=(2x−4)*(2x−4)*(2x−4)

=(2x+−4)(4x^2+−16x+16)

=(2x)(4x^2)+(2x)(−16x)+(2x)(16)+(−4)(4x^2)+(−4)(−16x)+(−4)(16)

=8x^3−32x^2+32x−16x2+64x−64

=8x^3−48x^2+96x−64
