Question

(x-3)(x-1)-(x-1)(x-4)+(x+2)+(x+4)-(x+1)(x-2)=17

Answer 1

Respuesta:

x=-1.25

Explicación paso a paso:

[(x-3)(x-1)=x²-x-3x+3=x²-4x+3]

(x²-4x+3)-[(x-1)(x-4)=x²-4x-x+4=x²-5x+4]

(x²-4x+3)-(x²-5x+4)=-9x-1

(-9x-1)+(x+2)=[(-8x+1)+(x+4)=-7x+5]

(-7x+5)-[(x+1)(x-2)=x²-2x+x+2=x²-x+2]

(-7x+5)-(-x+2)=-8x+7=17

-8x+7=17

-8x=17-7

-8x=10

x=10/-8

x=-1.25

Espero haberte ayudado.
