Answer:
<h2>x=0</h2>
Step-by-step explanation:
4x+4=4
-4 to get 4x alone
4x=0
therefore x=0
5/6 + 1/4
multiply the denominators and numerators in order for equation to have the same denominators to help solve.
20/24 + 6/24
= 26/24
= 13/12

Answer:
The last equation x2 - 2x -4 = 0
has solution (x - 1)^2 - 5 = 0, x = 1 + root(5) or x = 1 - root(5)
Step-by-step explanation:
If a quadratic function has roots 1 and 5
f(x) = (x -1)(x- 5)
f(x) = x^2 - 6x + 5
Unless you meant. -4 and 6 ?
g(x) = (x + 4)(x - 6)
g(x) = x^2 -2x -24
-------------------------
Or did you mean x = 1 and x =4 ?...
x^2 + 2x + 4 = 0 : complete square x^2 + 2x + 1 + 3 = 0, (x+1)^2 + 3 = 0
x^2 - 2x + 4 = 0 : complete square: (x -1)^2 + 3 = 0
0x^2 + 2x - 4 = 0, 2x - 4 = 0, x = 2
x^2 - 2x - 4 = 0 becomes: x^2 - 2x + 1 - 1 -4 = 0 ; (x - 1)^2 - 5 = 0
Answer:
9.8 X 10^-07
Step-by-step explanation:
When you have a number like that then you move the decimal how many time you can to the right so it can be a single digit and remember this when you have scientific notation then the number cant go past 10 and it cant go below 0.
1/4 because 3 parts of the circle are coloured but 1 part is not and 3+1=4. And that leftover as a fraction is 1/4
