Write down the roots of quadratic equation Ax2-bx=0
IgorC [24]

Answer:

x = 0, x = \frac{b}{a}

Step-by-step explanation:

Given

ax² - bx = 0 ← factor out x from each term

x(ax - b) = 0 ← in factored form

Equate each factor to zero and solve for x

x = 0

ax - b = 0 ⇒ ax = b ⇒ x = \frac{b}{a}

Drag a statement or reason to each box to complete this proof.
Vadim26 [7]
The items below show the complete steps as to how this is being answered.

  1. 3x - 4 = 14 >>>> Given
   2. 3x - 4 + 4 = 14 + 4 >>>
      Step number 2 above is an addition property of equality. Both sides of the equation are added with 4. 
  3. Simplifying >>>
      3x = 18
   4. 3x/3 = 18/3 >>>> Division property of equality
   5. >>>> Simplifying,
        x = 6

Hence, the order of the choices as answers is C, E, B, A, D.

3/14 and 19/63 whats the LCM
levacccp [35]
Factor them and find the common grouping

3/14
3 is prime so no factoring of this fraction

19/63, 63 is prime so no factoring


if ya wanted the least common denomenator then
14 and 63
14=2*7
63=7*9
so the least common denomenator would be 2*7*9=126
3/14 and 19/63 turns into 27/126 and 38/126
