Answer:
step 1. Halve everything
x^2+ 4x - 0.5 = 0
step 2. Halve the coefficient of x so you can write down an equivalent for x² + 4 (that is, (x + 2)^2 - 4 )
(x + 2)² - 4.5 = 0
step 3. Isolate the squared term:
(x + 2)^2 = 4.5
step 4. Take square roots of both sides, recognising that a square root can be positive or negative:
x + 2 = ±√4.5
step 5. Make x explicitly
x = -2 ±√4.5
And there you are with two solutions.

Answer:
The value of given expression is 13 / 3
Step-by-step explanation:
Given expression in the form of improper fraction;
17/3 - 
Find;
The value of given expression
Computation:
⇒ 17/3 -
Step 1 ;
Change mixed fraction into simple fraction
⇒ 17/3 - 4/3
Step 2 ;
By taking LCM of denominators;
⇒ [17 - 4] / 3
Step 3 ;
Subtract 17 from 3
⇒ [13] / 3
The value of given expression is 13 / 3
Answer:
Fewer than means that something is less than another thing. For example, the number 2 is fewer than the number 4. There's also this cool symbol that you can use instead of writing the words 'fewer than'. You could say for example 2<4. A fun way to remember which way the symbol points is to imagine it like an alligator, the number 2 is trying to eat the number 4 to grow!
