Bez . factonzo los siguienes trinomas de a ayuda doy coronita forma X Х + bx+c​

Answer 1

Respuesta:

A) x^2+5x+6

= x^2+3x+2x+6

= x(x+3)+2(x+3)

= (x+3)(x+2)

B) x^2-14x+24

= x^2-12x-2x+24

= x(x-12)-2(x-12)

= (x-12)(x-2)

C) x^2+8x+7

= x^2+x+7x+7

= x(x+1)+7(x+1)

= (x+1)(x+7)

D) x^2-9x+14

= x^2-2x-7x+14

= x(x-2)-7(x-2)

= (x-2)(x-7)

A) 2x^2+5x+3

= 2x^2+3x+2x+3

= x(2x+3)+(2x+3)

= (2x+3)(x+1)

B) 2x^2+x-6

= 2x^2-3x+4x-6

= x(2x-3)+2(2x-3)

= (2x-3)(x+2)

C ) 4x^2-4x-3

= 4x^2-6x+2x-3

= 2x(2x-3)+(2x-3)

= (2x-3)(2x+1)

D) 2x^2-x-10

= 2x^2-5x+4x-10

= x(2x-5)+2(2x-5)

= (2x-5)(x+2)
