Question

sa se dezvolte binomul la putere (4-x)^4.DAU COROANA!!!

Answer 1

(a - b)^4 = (a^4 - 4ba^3 + 6a^2b^2 - 4ab^3 + b^4)

(4 - x)^4 = 4^4 - 4*x*4^3 + 6*4^2*x^2 - 4*4*x^3 + x^4 =

                256 - 256x + 96x^2 - 16x^3 + x^4

Answer 2

(4-x)⁴=

(4²-2×4x+x²)(4²-2×4x+x²)=

(16-8x+x²)(16-8x+x²)=

16(16-8x+x²)-8x(16-8x+x²)+x²(16x-8x+x²)=

256-128x+16x²-(128x-64x²+8x³)+16x²-8x³+x⁴=

256-128x+16x²-128x-64x²+16x²-8x³+x⁴=

256+(-128x-128x)+(16x²+64x²+16x²)+(-8x³-8x³)+x⁴=

256-256x+96x²-16x³+x⁴
