6x^2 - 2x + 1 is a quadratic formula from the form ax^2 + bx + c. This form of equation represents a parabola.
Finding 6x^2 - 2x + 1 = 0, means that you need to find the zeroes of the equation.
Δ = b^2 - 4ac
If Δ>0, the equation admits 2 zeroes and 6x^2 - 2x + 1 = 0 exists for 2 values of x.
If Δ<0, the equation doesn't admit any zero, and 6x^2 - 2x + 1 = 0 doesn't exist since the parabola doesn't intersect with the axe X'X
If Δ=0, the equation admits 1 zero, which means that the peak of the parabola is touching the axe X'X.
In 6x^2 - 2x + 1, a=6, b=-2, and c =1.
Δ= b^2 - 4ac
Δ=(-2)^2 - 4(6)(1)
Δ= 4 - 24
Δ= -20
Δ<0 so the parabola doesn't intersect with the Axe X'X, which means there's no solution for 6x^2 - 2x + 1 = 0.
I've added a picture of the parabola represented by this equation under the answer.
Hope this Helps! :)

3u - 2v + w gives the resultant vector as; <49, 19>
8u - 6v gives the resultant vector as; <184, 60>
7v - 4w gives the resultant vector as; <61, 104>
u - 5w gives the resultant vector as; <-9, 37>
<h3>How to find the resultant of vectors?</h3>
We are given the vectors;
u = 11i + 12j
v = -16i + 6j
w = 4i - 5j
1) 3u - 2v + w gives the resultant vector as;
3(11i + 12j) - 2(-16i + 6j) + 4i - 5j
⇒ 33i + 36j + 32i - 12j + 4i - 5j
⇒ 49i + 19j
⇒ <49, 19>
2) 8u - 6v gives the resultant vector as;
8(11i + 12j) - 6(-16i + 6j)
⇒ 88i + 96j + 96i - 36j
⇒ 184i + 60j
3) 7v - 4w gives the resultant vector as;
7(11i + 12j) - 4(4i - 5j)
⇒ 77i + 84j - 16i + 20j
⇒ 61i + 104j
4) u - 5w gives the resultant vector as;
11i + 12j - 5(4i - 5j)
11i + 12j - 20i + 25j
-9i + 37j

Answer:
The x intercept is (12,0)
Step-by-step explanation:
1.5x+4.5y=18 Subtract 1.5 x from both sides of the equation
4.5y=-1.5x+18 Divide both sides of the equation by 4.5
4.5y/4.5=-1.5x/4.5+18/4.5
y=-1/3x+4
The slope is -1/3
The y intercept is (0,4)
To find the x intercept, yet y=0 and solve.
1.5x+4.5y=18
1.5x+4.5(0)=18
1.5x=18 Divide both sides of the equation by 1.5
1.5x/1.5=18/1.5
x=12
4) -0.3 = -1/3 < -1/7 since the bigger a negative number is the less positive it is. 1/8 is positive so it is clear that it should be placed last. & thus do all options this way.
5) B
Area of a triangle = ½ bh.
where b = base &
h = height.
Area of outer shape = (½ x 16 x 12) in^2.
= 96 in^2.
Area of unshaded inner shape = (½ x 3 x 4) in^2.
= 6 in^2.
Area of shaded region = (96 – 6) in^2.
= 90 in^2.
