Question
The coefficient of 𝑥 in the product (𝑥 − 3) (𝑥 − 5) is
- 2
- 8
- -8
- 15
Hint:
- Multiplication of polynomials.
- Distributive identity:
- a (b + c) = ab + ac.
The correct answer is: -8
Answer:
- Step by step explanation:
- Given:
(x - 3) (x - 5)
- Step 1:
Product
(x - 3) (x - 5)
x (x - 5) - 3 (x - 5)
a (b + c) = ab + ac
x2 - 5x - 3x + 15
x2 - 8x + 15
hence, coefficient of x is -8.
- Final Answer:
Correct option C. -8.
- Given:

Graph the equation 
We can find the tabular values for any points of x and then plot them on the graph. But we usually choose values for which calculating y is easier. This makes plotting the graph simpler. We can also find the values by putting different values of y in the equation to get different values for x. Either way, we need points satisfying the equation to plot its graph.
