Question

Are 2-1 are solutions for x²-3x+2​

Answer 1

Answer:

$hey$

Step-by-step explanation:

Solve Quadratic Equation using the Quadratic Formula

3.3 Solving x2-3x+2 = 0 by the Quadratic Formula .

According to the Quadratic Formula, x , the solution for Ax2+Bx+C = 0 , where A, B and C are numbers, often called coefficients, is given by :

- B ± √ B2-4AC

x = ————————

2A

In our case, A = 1

B = -3

C = 2

Accordingly, B2 - 4AC =

9 - 8 =

1

Applying the quadratic formula :

3 ± √ 1

x = ————

2

So now we are looking at:

x = ( 3 ± 1) / 2

Two real solutions:

x =(3+√1)/2= 2.000

or:

x =(3-√1)/2= 1.000

Two solutions were found :

x = 2

x = 1
