Answer:
What's '2−7x'
Step-by-step explanation:
Answer:
x = - 2, x = 0
Step-by-step explanation:
- 3x² - 6x ← factor out - 3x from each term
= - 3x(x + 2)
To solve equate to zero
- 3x(x + 2) = 0
Equate each factor to zero and solve for x
- 3x = 0 ⇒ x = 0
x + 2 = 0 ⇒ x = - 2
Answer: half the number?
If you write an equation for it:
Let the number be x
1/2x = x - 1/2x
