The simplest form can be 13/3: 7 or 4.3:7
Answer:
Step-by-step explanation:
The easiest way to determine the answer to your question is to evaluate the
discriminant
For a quadratic in the form:
y
=
a
x
2
+
b
x
+
c
the
discriminant
) is equal to
b
2
−
4
a
c
For your example
4
x
2
+
8
x
+
3
=
0
The
discriminant
is
Δ
=
8

Use the distributive property to multiply 0.25 by x−6.
combine 
and 0.25x to get x.
Add −1.5 and 28.4 to get 26.9.

Answer:
2/4 = 1/2
Step-by-step explanation:
Firstly expand cos(x - 30)....which is..
[cos x.cos 30 + sin x.sin 30]
If sin x = -1/2...then cos x = square root of 3/2
Then substitute the values into the expansion above....which...,
[(square root of 3/2)(square root of 3/2) + (-1/2)(1/2) ]
; 3/4 - 1/4 = 2/4
;Ans = 2/4 = 1/2
