Plug it into the quadratic formula (you'll get two answers):
1. -12+-√12^2-4(3)(11)
_________________
2(3)
2. -12+-√12
________
6
3. -12+√12 and -12-√12
_______ _______
6 6
The product asked above may be given expressed by the expression,
(2) x (sqrt 3) times (sqrt 12)
Two is also equivalent to sqrt of 4. The operation may be expressed as,
(sqrt 4) x (sqrt 3) x sqrt (12)
The product is sqrt (144). This gives an answer of 12 and it is rational.
A system of linear equations that must be solved algebraically is when numbers are very large or very small or when those that have to be accurate to several decimal places which is hard to graph.

Negative StartFraction 15 Over 2 EndFraction
Step-by-step explanation:
Slope or gradient of a line is the ratio of change in y co-ordinates to the change in x co-ordinates.
Therefore;
M=∆y÷∆x
The change in y co-ordinates is given by
∆y=y2-y1
Similarly, change in x co-ordinates is given by
∆x=x2-x1
Given the two points as (5, 80) and (7, 65)
X1=5 Y1=80
X2=7 Y2=65
∆y=65-80=-15
∆x=7-5=2
Hence ∆y÷∆x will be -15÷2=-7.5 or -7½
