Step-by-step explanation:
Answer:
2 irrational solutions
Step-by-step explanation:
using the quadratic formula:
3x²−x−5=0
where a = 3, b = -1 and c = -5, plug in those values in the quadratic formula
you get two solutions:
both can be written as:
They are irrational as they cannot be written in the form p/q where p and q are whole numbers (integers)
Step-by-step explanation:
Let x represent the first number, and y be the second number.
The first statement can be modeled as
The second statement can modeled as
If we multiply 2 both sides of the first equation,
Subsitue this for 30 in second equation,
Subsitue this for y in either equation,
So our answer is
plus or minus sqr root of 15, 0).
