Find the following when a = -1, b = 2, c = -1/4
(4b - 3)/(2a) -1

We substitute the given into the equation
given: a=-1, b=2, c=
=(-1
=-1
=-1
=-1
to continue, we can either find a common denominator or change the fraction to decimal.
Fraction to Decimal:
=-2.5
Equation=-2.5-1=-3.5
OR Common Denominator:
=×         (denominator should be -2=common)
=+
=
which also = to -3.5

It’s d not so sure because i think it is
