How do you factor 2x squared minus13x plus 20 equals 0?
Usually the easiest way to solve this kind of problem is to find two numbers whose sum is equal to the coefficient of the middle term, and whose product is equal to the product of the coefficients of the first and last terms. So in this case, we would want a product of 40, and a sum of -13. The only numbers that meet that condition are -8 and -5, so we'll use those, breaking the middle term down into two separate terms: 2x2 - 13x + 20 = 0 ∴ 2x2 - 8x - 5x + 20 = 0 Now you can take a common factor out of both the first two terms and the last two terms, and group the like terms together, resulting in the answer you seek: ∴ 2x(x - 4) - 5(x - 4) = 0 ∴ (2x - 5)(x - 4) = 0 ∴ x ∈ {2.5, 4}

Find the sum of an arithmetic progression of seventeen terms whose middle term is 5?
85 (=17*5). The middle term is 5. There are 8 terms bigger than 5 and 8 smaller. The term smaller than 5 and next to it is 5 - r The term bigger than 5 and next to it is 5 + r So these two average 5. Similarly, the next pair outwards average 5; and so on. So the sum of the progression is equivalent to the sum of 8 pairs of numbers whose average is 5 and the middle term which is 5 ie 17 lots of 5.

Find the slope of the line whose equation is 4x - 6y 8?
Without an equality sign the given terms can't be considered to be a straight line equation.
What is the median for these numbers 90 91 92 93 94 95 96 97 98 99 100?
90, 91,92,93,94,95,96,97,98,99,100. There are eleven terms. To find the median, you take the absolute middle term. The absolute middle term is '95'. NB You will notice that there are five terms to the left of 95, and five terms to the right of 95.
