You’re going to need to add a picture to the problem it cannot be solved with just this information
Factors are (3x + 5) and (x - 2). Zeros are -5/3 and 2.
Step-by-step explanation:
- Step 1: Given quadratic equation 3x² - x = 10 ⇒ 3x² - x - 10 = 0
- Step 2: Use factoring method (product and sum rule) to find factors and zeros. So the equation can be written as below.
⇒ 3x² - 6x + 5x - 10 = 0
⇒ 3x(x - 2) + 5(x - 2) = 0
⇒ (3x + 5)(x - 2) = 0 These are the factors of the equation.
- Step 3: Find zeros by equating the factors to 0.
⇒ 3x + 5 = 0 and x - 2 = 0
⇒ x = -5/3 and 2
Answer:
Step-by-step explanation:
Cost price of the article = Rs 400
Selling price of the article = Rs 420
As, S.P > C.P
Profit = S.P – C.P
= Rs( 420 – 400)
⠀⠀⠀= Rs 20
So,
Profit percent = (20/400 × 100)%
⠀⠀⠀⠀⠀⠀⠀⠀ = (20/4) %
⠀⠀⠀⠀⠀⠀⠀⠀ = 5 %
