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

Answers

We substitute the given into the equation
given: a=-1, b=2, c=(-1)/(4)
=((4b-3)/(2a)-1
=(4(2)-3)/(2(-1))-1
=(8-3)/(-2)-1
=(5)/(-2)-1
to continue, we can either find a common denominator or change the fraction to decimal.
Fraction to Decimal:
(5)/(-2)=-2.5
Equation=-2.5-1=-3.5
OR Common Denominator:
=(5)/(-2)(-1)/(1)×(-2)/(-2)         (denominator should be -2=common)
=(5)/(-2)+(2)/(-2)
=(7)/(-2)
which also = to -3.5
