4.3 Solving 3x2-2x-1 = 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 = 3
B = -2
C = -1
Accordingly, B2 - 4AC =
4 - (-12) =
16
Applying the quadratic formula :
2 ± √ 16
x = —————
6
Two real solutions:
x =(2+√16)/6
or:
x =(2-√16)/6
Answer:10/3
Step-by-step explanation:
5=2/3x
2/3(5)=2/3(2/3x)
10/3=x
Width = Length - 2
Area = L x W
y = x * ( x - 2 )
If the point is ( 2, 0 ): x = 2, y = 0
y = 2 * ( 2 - 2 ) = 2 * 0 = 0 ( area )
Answer:
B ) The area is 0 if the length is 2.
