Sagot :
Answer:
x² -3x + 1.5
Explanation:
Here using the formula: [tex]\left[\begin{array}{ccc}x = \frac{ -b \pm \sqrt{b^2 - 4ac}}{2a} \end{array}\right][/tex]
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
