which method of solving the quadratic equation would be the easiest to find the soulution for 2x^2 - 4x-3=0
svetlana [45]
Solve for x over the real numbers:
2 x^2 - 4 x - 3 = 0

Divide both sides by 2:
x^2 - 2 x - 3/2 = 0

Add 3/2 to both sides:
x^2 - 2 x = 3/2

Add 1 to both sides:
x^2 - 2 x + 1 = 5/2

Write the left hand side as a square:
(x - 1)^2 = 5/2

Take the square root of both sides:
x - 1 = sqrt(5/2) or x - 1 = -sqrt(5/2)

Add 1 to both sides:
x = 1 + sqrt(5/2) or x - 1 = -sqrt(5/2)

Add 1 to both sides:
Answer: x = 1 + sqrt(5/2) or x = 1 - sqrt(5/2)

Andreyy89

Answer:

50 for part 1. 1/2 for part 2. Part 3 As likely as not.

Step-by-step explanation:

For part 1, To write the decimal as a​ percent, write the decimal as a fraction with denominator 100. The numerator of the fraction is the percent.

For part 3, The probability of an event is a number from 0 to 1 that measures the likelihood the event will occur. If the probability is between 0 and​ 0.5, the event is unlikely to occur. If the probability is between 0.5 and​ 1, the event is likely to occur. If the probability is​ 0.5, the occurrence of the event is as likely as not.
