Question

Desenvolva :
A) (0,8 + x³)²
B) (b - 3x²)²
C) ( 2y^5 + 1,3x³)²

Answer 1

A) ( 0,8 + x3 )2 = ( 0,8 )2 + 2. 0,8 .x3 + ( x3 )2 =

                              0,64 + 1,6x3 + x6

B) ( b - 3x2 )2 =     b2 - 2 . b. 3x2 + ( 3x2 )2 =

                              b2 - 6 bx2 + 9x4

C) ( 2y5 + 1,3x3 )2 = ( 2y5 )2 + 2 .2y5.1,3x3 + ( 1,3x3 )2 =

                                   4y10 + 5,2x3 y5 + 1,69x6
