−2x^2+3x+20why is this equation so special it is in standard form, and when i solve for zeros
i factor down to
-1( 2x^2-3x-20)
factor
( 2x^2-3x-20)
factor by grouping 2(-20)=-40 what numbers multiple to equal -40 and add to equal -3
-8(5) = -40
-8+5= -3
and then just to find zeros the...
The Role of H in the quadratic function ( vertex form)
i get that this is how its written on a graph y=(x-2)^2+k
that the graph looks as if the value of h is positive as in +2 ( however its value is actually negative)
looks like it shifted right my textbook contradicts itself
y=3(x-1)^2 +2...
