How to solve it and why
RideAnS [48]
6.

4x^2 + 4 = 0

Divide both sides by 4

x^2 + 1 = 0

Use the quadratic formula since this cannot be factored.

x = (-b +- sqrt(b^2 - 4ac))/(2a)

x = +- sqrt(-4(1)(1))/2

x = +- sqrt(-4)/2

x = +- 2i/2

x = +- i

x = i or x = -i

Quicker solution:

If you have x^2 = number, then

x = +- sqrt(number)

Once you get to

x^2 + 1 = 0

Subtract 1 from both sides

x^2 = -1

Apply the quick method

x = +- sqrt(-1)

x = +- i

8.

2x^2 + 50 = 0

Divide both sides by 2

x^2 + 25 = 0

Subtract 25 from both sides

x^2 = -25

Apply quick method

x = +- sqrt(25)

x = +- 5i

x = 5i or x = -5i

A car originally costs $20,000. Its price went up by 20% and then by another $8,000. How much did the price go up as a percentag
Nataliya [291]

Answer:

60%

Step-by-step explanation:

20,000

we can move the decimal place one to the left to find 10 percent

2,000

multiply 10 x 2 to find twenty percent or 4,000

we add this to the original total. 24,000

then add the 8,000

32,000

we know find one percent of the original total

200

and find the difference between the two totals

32000-20000 = 12,000

12000 divided by 200 which is 6

multiply six by ten to get

60 percent
