2x² + 3x -8 = 0
a = 2 , b = 3 , c = -8
So..
D = b²-4ac = 9 + 64 = 73
for bigger solution , use x = -b + √D / 2a
For smaller solution, use x = -b - √D / 2a
So
= -3 + √73 / 2. 2
= 1/4 (√73 -3)
Hopefully helpfull.. ^_^
Part A
Distribute the one-half.
1.24g + 0.87m + 0.98z
Part B
(29.68 - x) + 14.45
Or simplified to 44.13 - x
Part C
a = number of times at the store
b = gloves' price
c = hat's price
I think you mean b is not equal to 0.
We have that 11.424242... = 11 + 0.424242...
Now let x = 0.424242...
Then 100x = 42.424242...
Now 99x = 100x - x = 42 so 99x = 42 and therefore x = 42/99
Now we can simplify 42/99 to 14/33
Now combining this we get 11.424242... = 11 + 14/33
= 363/33 + 14/33 = 377/33
We have

So

The rational term vanishes as <em>x</em> gets arbitrarily large, so we can ignore that term, leaving us with

and this happens if <em>a</em> = 1 and <em>b</em> = -1.
To confirm, we have

as required.
