Question

1. Sa se calculeze :
a ) ( x²+x)² =
b) ( 4xy - 2 ) ² =
c ) ( 3x²y+y²) ² =
d) ( 4x²- y ) ²
e ) ( x² v2 + x ) ²

URGENT !!

Answer 1

a) (x²+x)² = x⁴+2x³+x² b) (4xy-2)² = 16x²y² - 16xy + 4 c) (3x²y + y²)² = 9x⁴y² + 6x²y³ + y⁴ d) (4x²-y)² = 16x⁴- 8x²y + y² e) ( x²v2 + x)² = x⁴v²4 + 4x³v + x² Sper ca te-am ajutat
