Answer:
2x² - 3x - 2
Explain:
Use the FOIL method: (a +b)(c +d) = ac + ad +bc +bd.
2x² + x - 4x - 2
Collect like terms.
2x² + (x - 4x) - 2
Simplify.
2x² - 3x - 2
If we plug the values, we have

So, we have to solve the following equation:

So, when we impose
, knowing the value of p, we have

And so the solution is

In the above question 13m=156 we are dividing both sides by 13 so that m=12 .As 
According to Division property of Equality: If you divide one side of an equation by a number, you also must divide the other side by the same number so that your equation stays the same.
The property Division Property of Equality is justified .
