Answer:
--3 ±sqrt((-3)^2 -4(4)(-9))
-------------------------------
2(4)
Step-by-step explanation:
4x^2-5=3x+4
We need to get this in standard form to answer the question
Subtract 3x from each side
4x^2-3x-5=3x-3x+4
4x^2-3x-5=+4
Subtract 4 from each side
4x^2-3x-9 =0
a = 4
b = -3
c = -9
-b ±sqrt(b^2 -4ac)
---------------------------
2a
--3 ±sqrt((-3)^2 -4(4)(-9))
-------------------------------
2(4)
Answer:
The variables change
Step-by-step explanation:
Since we can't subtract c from -b we multiply both variables by a because the question is telling us to subtract b and c then multiply the awnser by a, but we don't know what b and c is so we just multiply b and c by a. In the end we get ab-ac
