Question
Which of the following is equivalent to 
?
- 5x
The correct answer is:
○ The concept used in this question is of additon of polynomials.
○ Arrange the term in the decreasing order of their power.
○ To add polynomials simply add any like terms together.
○ Like terms are terms whose variables and exponents are the same.
- Step by step explanation:
○ Given:
The expression: 2(x2 − x) + 3(x2 − x)
○ Step 1:
○ Simplify the expression
2(x2 − x) + 3(x2 − x)
2x2 - 2x + 3x2 - 3x
○ Step 2:
○ Arrange the term in the decreasing order of their power
∴ 2x2 + 3x2 - 2x - 3x
5x2 - 5x
Hence, the polynomial equivalent to expression 2(x2 − x) + 3(x2 − x) is
5x2 - 5x.
- Final Answer:
Correct option is,
Option A. 5x2 - 5x.
