The value of (x-1)^2 at scores 1,2,1, and 4 are 0,1,0,8 respectively.
Quadratic equations are the polynomial equations of degree 2 in one variable of type [tex]ax^2+bx+c[/tex] where a,b,c are constant and the x is variable.
Now from the given question we have [tex](x-1)^2[/tex].
[tex](x-1)^2=x^2-2x+1[/tex]
Now we will find the value of scores 1,2,1,4 by putting in the equation.
At
[tex]x=1 \ \ \ =(1-1)^2=0\\\\\\x=2\ \ \ =(2-1)^2=1\\\\\\x=1\ \ \ =(1-1)^2=0\\\\\\x=4\ \ \ =(4-1)^2=8[/tex]
Hence the value of (x-1)^2 at scores 1,2,1, and 4 are 0,1,0,8 respectively.
