Question

●(x-2)²+x(x-3)=3(x+4)(x-3)-(x+2)(x-1)+2.
●(3x-1)²-5(x-2)-(2x+3)²-(5x+2)(x-1)=0.
● 2(x-3)-3(x+1)+(x-5)(x-3)+4x*–5x+1)=4x²-12. ● 5(x-2)²-5(x+3)2+(2x-1)(x+2) - 10x =0. ●x²-5x+15=x(x-3)-14+5(x-2)+3(13-2x).
●3(5x-6)(3x+2)-6(3x+4)(x-1)-3(9x+1)(x-2)=0.
●7(x-4)²-3(x+5)²=4(x+1)(x-1)-2.
●5(1-x)²-6(x²-3x-7)=x(x-3)- 2x(x+5)-2​

Explicación paso a paso:

Answer 2

[tex]\left(x-2\right)^2+x\left(x-3\right)=3\left(x+4\right)\left(x-3\right)-\left(x+2\right)\left(x-1\right)+2\quad :\quad x=4[/tex]

Paso 1

[tex]\left(x-2\right)^2+x\left(x-3\right)=3\left(x+4\right)\left(x-3\right)-\left(x+2\right)\left(x-1\right)+2[/tex]

Paso 2

[tex]2x^2-7x+4=2x^2+2x-32[/tex]

Paso 3

[tex]2x^2-7x=2x^2+2x-36[/tex]

Paso 4

[tex]-9x=-36[/tex]

Paso 5

[tex]x=4[/tex]

[tex]\left(3x-1\right)^2-5\left(x-2\right)-\left(2x+3\right)^2-\left(5x+2\right)\left(x-1\right)=0\quad :\quad x=\frac{1}{5}[/tex]

Paso 1

[tex]\left(3x-1\right)^2-5\left(x-2\right)-\left(2x+3\right)^2-\left(5x+2\right)\left(x-1\right)=0[/tex]

Paso 2

[tex]-20x+4=0[/tex]

Paso 3

[tex]x=\frac{1}{5}[/tex]
