Orleans-hanna Algebra Prognosis Test Solved Problems

Pro 1:-Find the sum of two algebraic expression that are given below

4x^2+3x+4 and 5x^2 +2x+12.

Solution:-The given algebraic expressions are the following.

4x^2+3x+4.

5x^2 +2x+12.

The sum of two expressions is

4x^2+3x+4 + 5x^2 +2x+12.

Now group the common terms together.

4x^2 + 5x^2 +3x + 2x + 4 + 12.

9x^2 + 5x + 16.

The simplified expression is 9x^2 + 5x + 16.

Pro 2:-Find the value of x in the given algebraic expression.

4x + 12 + x + 3x = 12x + 3x + 2

Solution:-The given algebraic expression is

4x + 12 + x + 3x = 12x + 3x + 2

Group the like terms together

4x +x + 3x + 12 = 12x + 3x + 2

Now add like terms together

4x +x + 3x gives 8x.
12x + 3x gives 15x.

Now,8x + 12 = 15x + 2

In next step subtract 2 on both side.

8x + 12 -2 = 15x + 2 - 2.

We get 8x +10 = 15

Now subtract 10 on both side

8x +10 – 10 = 15x – 10

By simplifying it we get

8x = 15x -10

Now subtract 15x on both sides of the above equation.

8x – 15x = 15x – 15x -10

-7x  = -10

Now divide by -7 on both sides
`(-7x)/(-7) = (-10)/(-7)`

X  =`(10)/(7)`

The answer for x is `(10)/(7)`
