Remaining part of task 3

Expression #2

Evaluate this expression: (x^2 + 2x - 3) / (x + 1) when x = 2

Step 1

In the first step, we substitute the value of x in the given expression, in nominators and in denominators

Step 2

First, i solve the nominator, here exponential term is solved as 2^2 = 2×2 = 4 . Then to solve the multiplication as 2×2 =4 the above expression changes as

Step 3

On performing addition and subtraction in nominators and denominators we proceed step by step

final answer= 5/3 = 1.6

Expression #3

Solve the following equation: 2x + 5 = 3(x - 2) + 1

This expression is a bit different from others because here the equivalent sign devide the expression in two halves. So im going to solve these one by one and then equate them.

Step 1

Step2

In this step i simply multiple 3 with the terms in parentheses to solve it

Step 3

In the following step just addition is performed to get i.e -6 +1= -5

step5

Because L.H.S is already in simplest form so both side can be equivalent as follow
L.H.S = R.H.S

On rearranged this equation
we get
5+5 =3x -2x

Step5

Here is the final answer we got
