Question

Write the quadratic equation in standard form: y=ax^2+bc+c that has the given solutions:

(number 9)

Answer 1

x=-b±√b²-4ac

--------------

2a

Answer 2

x² -3x + 1.5

Step-by-step explanation:

Here using the formula:
`\left[\begin{array}{ccc}x = ( -b \pm √(b^2 - 4ac))/(2a) \end{array}\right]`

we can determine a

2a = 2

a = 1

we can determine b

-b = 3

b = -3

we can determine that b = -3

then using a = 1 , b = -3

find c:

(-3)²-4*1*c = 3

9-4c = 3

-4c = -6

c = 3/2

so the quadratic formula is x² -3x + 1.5
