Tips and Tricks To Solve Algebra

Note – Now as you have revised the identities, let us move forward and look up for some of the type of questions that are asked from this topic.

Type 1: Evaluation or finding the value of a variable

Question 1:

Find the value of x in 5x + 2 – 3x = 10

Options

A. 4
B. 3
C. 1
D. None of the above

Correct Answer: A
Explanation:

5x + 2 – 3x = 10
5x -3x +2 = 10
2x = 10-2
2x= 8
X= 4

Type 2: Tips and Tricks and Shortcuts for Algebra by Substitution Methods

Question 1.

What is the value of 2 (3a- 5)+ 2b (2- 6b) =10 when a= 2 and b =3?

Options

A. 89
B. 23
C. 18
D. None of the above

Correct Answer: C
Explanation:

2 (3a- 5)+ 2(2a- 6b) =10
6a – 10a + 12b = 10
Substituting the values, we get
6 * 2 -10 *2 + 12 *3 = 10
12 – 20 + 36 =10
12 – 20 + 36 -10 = 0
18

Question 2.

\frac{a(b-c)^{2}}{(c-a)(a-b)} + \frac{b(c-a)^{2}}{(a-b)(b-c)} + \frac{c(a-b)^{2}}{(b -c)(c-a)} =?

Options

A. a +b +c
B. a^{2} + b ^{2} + c ^{2}
C. 3
D. abc

Correct Answer: A
Explanation:

Degree of \frac{a(b-c)^{2}}{(c-a)(a-b)} = \frac{1+2}{1+1} = \frac{3}{2} = 3 -2 =1

Degree of \frac{b(c-a)^{2}}{(a-b)(b-c)} = \frac{1+2}{1+1} = \frac{3}{2} = 3 -2 = 1

Degree of \frac{c(a-b)^{2}}{(b -c)(c-a)} = \frac{1+2}{1+1} = \frac{3}{2} = 3 -2 =1

Therefore, Degree of overall expression is 1.

Therefore, according to the given options :-

Degree Of Option A – 1
Degree Of Option B – 2
Degree Of Option C – 0
Degree Of Option D – 3

Hence, Option a +b +c is the correct option
