x = 9/2 or x = -2 Solved by using the quadratic equation formula.
f(x) = 2*(x-3)*(x+2)/(x-1) for x ≠1
Correct form. 2X^2 - 2X - 1 = 0 - b +/- sqrt(b^2 - 4ac)/2a quadratic formula a = 2 b = - 2 c = -1 -(-2) +/- sqrt[(-2)^2 - 4(2)(-1)]/2(2) 2 +/- sqrt( 4 + 8)/4 2 +/- 2sqrt(3)/4 exact answer, less final factoring
Use the quadratic formula, with a = 1, b = -3, c = 2.
x2+8x+12 = 0 When factorized: (x+6)(x+2) = 0 Therefore: x = -6 or x = -2
No. Diameter = 2 x r
Radius time 2 equals the diameter.
The formula given is schools is circumfrence=2(pi)radius. But since I am a rebel, I use diameter times pi. This works since diameter equals 2 times radius. If you don't know, pi exactly equals 22 divided by 7. Or 3.14159.....as for an example, if you have a circle with diameter of 2, then you plug it in the formula. Then get your answer or 2(pi).
[2 x pie x radius] or [pie x diameter]
Diameter of circle = 2 * Radius of the circle.
The formula to determine speed is speed = distance / time. To determine the diameter of a circle, the formula is diameter = 2 x radius.
diameter = circumference / pi diameter = radius * 2
The diameter of a circle is twice its radius.
2 radiuses make the diameter
If you are given the radius of the circle, you can use the formula: diameter = 2*radius If you are given the circumference of the circle, you can use the formula: diameter = circumference/pi
The formula to calculate the outside diameter of a circle is: outside diameter = diameter + (2 * thickness). This formula takes into account the thickness of the circle's material when calculating the overall dimension.
Diameter = 2*Radius
