Answer:
1 ± i(1/2)√2
Step-by-step explanation:
Write this quadratic in standard form: subtract 3 from both sides. This results in 2x^2 - 4x - 3 = 0. Let's apply the quadratic formula. The coefficients of the x terms are 2, -4 and -3, so the discriminant is (-4)^2 - 4(2)(-3), or 16 - 24 = -8.
Following the format of the quadratic formula, we get
-(-4) ±i2√8 4 ±i2√2
x = ----------------- = --------------- = 1 ± i(1/2)√2

Answer:
Step-by-step explanation: Alright adding fractions here we go.
3 3/5 + 2 1/4
First add up the whole numbers. 3+2=5
Then adding the mix numbers, what you need to do is find a common demoninator. What do 5 and 4 both go into? Well 20, so we multiply each demoinator to get 20.
3/5+1/4
12/20 + 5/20
17/20
Answer is 5 17/20.
Answer:
479.33
Step-by-step explanation:
10/30 is the same as 1/3 or 33.34%.
Multiply the fraction to the original price then subtract.
719 * 1/3 = 239.67
719 - 239.67 = 479.33
Best of Luck!
