Question

1. x2 (x + 1) =

2. n2 (n – 1) =

3. x2 (3x2 – 2x + 3)

4. a (a + b – 1)=

5. xy ( 3xy + 2) =

Answer 1

Respuesta:

dame corona

Explicación paso a paso:

1. x2 (x+1)=

2x×(x+1)=

2x×x +2= 2x^2 + 2x

2. n2 (n-1)=

2n×(n-1)=

2n×n - 2n= 2n^2- 2n

3. x2 (3×2- 2x + 3)=

2x (6- 2x +3)=

2x (9 -2x) = 18x - 4x^2

4. a ( a+ b -1)=

a×a + a×b - a×1= a^2 + ab -a

5. xy ( 3xy + 2) =

xy× 3xy + 2 xy = 3 x^2 y^2 + 2xy
