Question

a.(x+2)(x+3) =
b. (x-1) (x-413
c.) (x-3) (x+4)=
d.) (x+51(x-1) =​

Answer 1

Răspuns:

$(x+2)(x+3)=x^2+5x+6\\(x-1)(x-413)=x^2-414x+413\\(x-3)(x+4)=x^2+x-12\\(x-1)(x+51)=x^2+50x-51$

Explicație pas cu pas:

Answer 2

Răspuns:

a.

$x {}^{2} + 3x + 2x + 6 = x {}^{2} + 5x + 6$

b.

$x {}^{2} - 413x - x + 413 = x {}^{2} - 414x + 413$

c.

$x {}^{2} + 4x - 3x - 12 = x {}^{2} + x - 12$

d.

$x {}^{2} - x + 51x - 51 = x {}^{2} + 50x - 51$
