How many real roots does the quadratic equation x 2 5x 6 0?

Answer: Using the quadratic formula, the roots of the equation x2 – 5x + 6 are 2 and 3.

Can you factor x 2 5x 6?

Given equation We need to find two numbers ‘a’ and ‘b’ such that a + b =5 and ab = 6. Thus, x+3 and x+2 are the factors of the polynomial x2 + 5x + 6.

What are the roots of quadratic equation x 2 5x − 6?

Answer: The roots of the quadratic equation x2 + 5x + 6 = 0 are -2 and -3.

What are the roots of the function x 2 5x 6 0?

The roots are x=2 and x=3 .

What is the absolute value of 6?

The absolute value of a number is its distance from 0. It is the magnitude of that number without considering its sign. Since 6 is six units away towards right from 0, the absolute value of 6 is just 6. The absolute value of 6 is written as |6| and is equal to 6.

How many solutions does x 2 5x 0 have?

Two solutions were found : x = 5. x = 0.

What are some examples of solving inequalities with modulus?

Solving Inequalities with Modulus – Examples. Example 1 : Solve the absolute value inequality given below |x – 9| < 2. and express the solution in interval notation. Solution :-2 < x – 9 < 2. Add 9 throughout the equation-2 + 9 < x – 9 + 9 < 2 + 9. 7 < x < 11. Hence the solution set of the above absolute inequality is (7, 11). Example 2 :

What is the value of X for every modulus?

Every modulus is a non-negative number and if two non-negative numbers add up to get zero then individual numbers itself equal to zero simultaneously. So, x = 2 is the only solution for this equation. Solution: Here the critical points are 1 and 2.

What is x2 – 5x + 6 = 0?

Every modulus is a non-negative number and if two non-negative numbers add up to get zero then individual numbers itself equal to zero simultaneously. x 2 – 5x + 6 = 0 for x = 2 or 3 x 2 – 8x + 12 = 0 for x = 2 or 6 Both the equations are zero at x = 2
