Question

E = (x + 2)⋅ (x + 7) + (x+4) (x-1) + 6
ayuda por favor ​

Answer 1

Respuesta:

E = (x+2)(x+7)+(x+4)(x-1)+6

E = (x)²+(2+7)x+(2×7)+(x)²+(4-1)x+(4(-1))+6

E = x²+9x+14+x²+3x+(-4)+6

E = (1+1)x²+(9+3)x+(14-4+6)

E = 2x²+12x+(10+6)

E = 2x²+12x+16

E = 2(x²+6x+8)

E = 2(x²+2x+4x+8)

E = 2(x(x+2)+4(x+2))

E = 2(x+2)(x+4) ==== > Respuesta .
