Question

3x+2(x+2)=20-(2x-5) ​

Answer 1

$\huge\color{yellow}{\underline{\underline{answer\::}}}$

• 3x + 2 (x +2) = 20 - (2x -5)

• 3x(x + 2) + 2(x + 2) = 20 - 2x + 5

• 3x² + 6x + 2x + 4 = 25 - 2x

• 3x² + 6x + 2x + 2x = 25 - 4

• 3x² + 10x = 21

• 3x² + 10x - 21 = 0

Answer 2

Answer:

3x + 2 (x +2) = 20 - (2x -5)

3x(x + 2) + 2(x + 2) = 20 - 2x + 5

3x² + 6x + 2x + 4 = 25 - 2x

3x² + 6x + 2x + 2x = 25 - 4

3x² + 10x = 21

3x² + 10x - 21 = 0
