Question
Find the sum of the following expressions.
(i) x + y + z, y – z, x – y, –x + z (ii) x2 + y2, 2x2, –3y2, 3x2 – 4y2
Hint:
The concept used in this question is the addition 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
The correct answer is: x + y + z
Answer:
- Step by step explanation:
○ Given:
Terms : x + y + z, y – z, x – y, –x + z
○ Step 1:
○ Simplify the expression.
∴ (x + y + z) + ( y – z) + ( x – y ) + ( –x + z )
○ Step 2:
○ Perform simple addition of like terms
(x + x – x) + ( y + y – y) + ( z – z + z )
x + y + z
- Final Answer:
x + y + z
(x + x – x) + ( y + y – y) + ( z – z + z ) x + y + zRelated Questions to study
