Answer:
-3 plus/minus square root 17 over 4
Step-by-step explanation:
2x squared = -3x + 1 is the same as 2x squared + 3x -1
a=2 b=3 c=-1
sub those into the formula and you get -3 plus/minus square root of 9 + 8 over 2×2
and then you simplify
That 2 means we multiply 4 by itself 2 times, and -4 x -4 = positive 16.
