Help ME !! Its A Math Problem! To avoid working with messy fractions when solving a quadratic equation by completing the square, the b value should be: negative

zero

odd

even

hello,

as we don't know if g(x) is continue,

answer b

f(x)=2x²-8x+1=2(x²-4x+4)+1-8=2(x-2)²-7

vertex is (2,-7) ( a minimum since coefficient of x² is > 0)

8.3 and the 3 is repeating

hope this .
