Answer:
It simplifies to 20x^2-7x-6.
Step-by-step explanation:
You could just make an area model and split it up into different boxes. So in the original form to the polynomial form:
divide your box into 4:
4x -3
------------------------
5x 20x^2 -15x
+2 +8x -6
-------------------------
So your basically multiplying by row. 4x*5x=20x^2, -3*5x=-15x, etc
So 20x^2 is alone so put that leading term in the equation. Next we have to similar terms -15x+8x simplifies to -7x and lastly your trailing term which is also alone
20x^2-7x-6
