How do I find the sum of 1 to 20?
The sum from 1 to n is n*(n+1)/2In this case that mean 20*21/2 = 210The sum from 1 to n is n*(n+1)/2In this case that mean 20*21/2 = 210The sum from 1 to n is n*(n+1)/2In this case that mean 20*21/2 = 210The sum from 1 to n is n*(n+1)/2In this case that mean 20*21/2 = 210

What does AM mean in math?
One meaning could be "Arithmetic Mean". Thus is you have a sample set containing number say 1, 4, 5, 2, 7, 9, 21, 12, then the Arithmetic mean would be the sum of the numbers divided by the number of numbers. In this case it would be (1 + 4 + 5 + 2 + 7 + 9+ 21 + 12)/8 = 61/8 = 7 and 5/8

Solve by completing the square of by quadratic equation -84x2 8x-12?
hmm... i don' think you have the completed the question. This one is pretty hard! Solving quadratics can be difficult and ompleting the square is one method for solving a quadratic equation.Is the equation -84x2-8x-12=0 or -84x2+8x - 12 = 0 or -84x2 = 8x - 12?If it is the first one:Factor out the 4:-4 (21x2 + 2x + 3) = 021x2 + 2x + 3 = 0 (divide by 21 each term to both sides)x2 + (2/21)x + 3/21 = 0 (subtract 3/21 to both sides)x2 + (2/21)x = -3/21 (add (1/2 of 2/21)2 or (1/21)2 to both sides)x2 + (2/21)x + (1/21)2 = -3/21 + 1/212(x + 1/21)2 = -63/212 + 1/212(x + 1/21)2 = -62/212 (square root to both sides)x + 1/21 = ± √-62/212x + 1/21 = ± (i/21)√62 (subtract 1/21 to both sides)x = -1/21 ± (i/21)√62x = -1/21 (1 - i√62) orx = -1/21 (1+ i√62)If it is the third one:-84x2 = 8x - 12 (divide by -84 to both sides)x2 = -(2/21)x + 3/21 (add (2/21)x to both sides)x2 + (2/21)x = 3/21 (add (1/2 of 2/21)2 or (1/21)2 to both sides)x2 + (2/21)x + (1/21)2 = 3/21 + 1/212(x + 1/21)2 = 63/212 + 1/212(x + 1/21)2 = 64/212 (square root to both sides)x + 1/21 = ± √64/212x + 1/21 = ± 8/21 (subtract 1/21 to both sides)x = -1/21 ± 8/21x = -1/21 + 8/21 = 7/21 = 1/3 orx = -1/21 - 8/21 = -9/21 = -3/7
