Respuesta :

Question:

→To simple the given equations

  • ( 2x + 1 ) + 5x
  • ( x + 3 ) ( x + 4 )
  • ( x + y ) ²
  • ( 2x + 1 ) ( x - 3 )

Answer:

Part 1:

[tex]\green{step \: 1}[/tex]

→[tex] 3 ( 2x + 1 ) + 5x[/tex]

[tex]\green{step \: 2}[/tex]

→[tex]6x + 3 + 5x[/tex]

[tex]\green{step \: 3}[/tex]

→[tex]\blue{11x + 3✓}[/tex]

part 2:

[tex]\green{step \: 1}[/tex]

→[tex]( x + 3 ) ( x + 4 )[/tex]

[tex]\green{step \: 2}[/tex]

→[tex] {x}^{2} + 4x + 3x + 12[/tex]

[tex]\green{step \: 3}[/tex]

→[tex]\blue{ {x}^{2} + 7x + 12✓}[/tex]

part 3:

[tex]\green{step \: 1}[/tex]

→[tex]( x + y ) ^2[/tex]

[tex]\green{step \: 2}[/tex]

→[tex] \blue{{x}^{2} + {y}^{2} + 2xy✓}[/tex]

part 4:

[tex]\green{step \: 1}[/tex]

→[tex] ( 2x + 1 ) ( x - 3 )[/tex]

[tex]\green{step \: 2}[/tex]

→[tex]2 {x}^{2} - 6x + x - 3[/tex]

[tex]\green{step \: 3}[/tex]

→[tex]\blue{2 {x}^{2} - 5x - 3✓}[/tex]
