Assuming simplify then
get rid of parenthasees by assuming that there is a 1 in front of each, so multply by 1 and get rid of partenthasees so
5p^2-3+2p^2-3p^3
add like terms
7p^2-3p^3-3
normally ordered with biggest exponenst to the left from left to right decending
so
-3p^3+7p^2-3
Answer:
ONE SOLUTION
Step-by-step explanation:
When two points on a line are given, the equation of the line is given by the formula:

where
and
are the points on the line.
Here, the first set of points are:
and
.
Therefore,
and
.
The line passing through this is given by:


∴ 2x + y - 1 =0
Now, for the second line, the points are:
and
.
Therefore, 

∴ 2x - y + 2 = 0
Now, to determine the number of solutions the two equations have, we solve these two equations,
Adding Eqn(1) and Eqn(2) we get:
4x = -1

And
.
Since, we arrive at unique values of 'x' and 'y', we say the lines have only one unique solution.
If this is a system of equations then:
Multiply 5x-y=3 by -2
=> -10x+2y=-6
Now you sum the equations:
10x-10x+7y+2y=-3-6
=> 9y=-9
Then just divide by 9: y=-1
Now to get x, choose one of the equations and use the value we got from y:
5x-(-1)=3 => 5x+1=3 => 5x=3-1
=> 5x=2
=> x=2/5
(x,y)=(2/5, -1)
