What is the value of 1 - 2x + 3x^2 - 4x + 5x - 6x + 7x^2 - 8x + 9 in terms of x? Express your answer in the form ax^2 + bx + c where a, b, and c are numbers.

Hello Guest!
\(f(x)=ax^2+bx+c\)
\(f(x)=10x^2-15x+10\)
\(a=10,\ b=-15,\ c=10\)
If f (x) = 0, then:
\(x^2-1.5x+1=0\\ x=0.75\pm \sqrt{0.5625-1}\)
\(x\in \{0.75-0.661438i,\ 0.75+0.661438i\}\)
