Question

Find the sum of the following expressions.
(i) 5x, – 3x, 4x, –10x

hint Hint:

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

The correct answer is: - 4x

Answer:

○        The concept used in this question is the addition of polynomials.
○

Step by step explanation:

○        Given:
                        Expression: 5x, –3x, 4x, –10x
○        Step 1:
○        Simplify the expression.
∴ ( 5x ) + (–3x ) + (4x) + (-10x )
○        Step 2:
○        Perform simple addition of like terms
   $rightwards double arrow$ 5x – 3x + 4x -10x
$rightwards double arrow$   - 4x

Final Answer:

- 4x
