Question

Solve, using factoring: 8x2 = 16x


Answers:

{0}

{-8, -16}

{0, 8}

{0, 2}

Answer 1

Solve for x over the real numbers:
8 x^2 = 16 x
Move everything to the left hand side.
Subtract 16 x from both sides:
8 x^2-16 x = 0
Factor the left hand side.
Factor x and constant terms from the left hand side:
8 x (x-2) = 0
Divide both sides by a constant to simplify the equation.
Divide both sides by 8:
x (x-2) = 0
Solve each term in the product separately.
Split into two equations:
x-2 = 0 or x = 0
Look at the first equation: Solve for x.
Add 2 to both sides:
Answer: |
| x = 2 or x = 0

Answer 2

nice solution wolframalpha

Answer 3

LOL

Answer 4

thanks

Answer 5

aaa thx, i got the answer already lol

Answer 6

its D

Answer 7

8x^(2) = 16x
8x^(2) - 16x = 0
8x(x - 2) = 0

8x = 0 ==> x = 0
or
x - 2 = 0 ==> x = 2

x = 0,2
