How do you find two real solutions of an equation?
It is called the Discriminant, because it can “discriminate” between the possible types of answer:
- when b2 − 4ac is positive, we get two Real solutions.
- when it is zero we get just ONE real solution (both answers are the same)
- when it is negative we get a pair of Complex solutions.
How many solutions does a quadratic equation have?
2 solutions
As we have seen, there can be 0, 1, or 2 solutions to a quadratic equation, depending on whether the expression inside the square root sign, (b2 – 4ac), is positive, negative, or zero. This expression has a special name: the discriminant.
How many real roots does the equation |X|^2-4|x|+4=0 have?
Originally Answered: The number of real roots of the equation |x|^2-4|x|+4=0 is? The number of real roots is 2: . The number of complex roots is infinite (a circumference) with radius 2 centered at the origin.
How many solutions does the equation ⇒(x+1)2 have?
⇒ (x+1)2 = 0 or no solution . Hence, given equation have only one solution . Was this answer helpful?
How to find the number of real solutions of a discriminant?
1] If the discriminant is positive you’ll have 2 separate real solutions x1 ≠ x2; 2] If the discriminant is equal to zero you’ll have 2 coincident real solutions, x1 = x2 (=two equal numbers…I know it is weird but do not worry);
What is the value of 3^x + x – 2 = 0?
3^x + x – 2 = 0 is the Equation. Let’s take y as 2. This is our equation. We just need to superimpose both the Graphs. When, X is less than 0 , Value of 3^x is between 0 to 1. Value of X will always be negative. Addition of 3^x + x will always be less than 1.
