It is 2704.
It cannot be factored because the discriminant of b2-4ac is less than zero.
One-houndred and thirty five.
It will be: 6x2 +8x -15
y = 6x2 + x -1 ?? discriminant = b2 - 4ac = 12 - 4(6)(-1) = 25
Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "equals" etc. And using ^ to indicate powers (eg x-squared = x^2).
When the given expression equals 0 then x = -1/6 and x = -6
9+6x2=21
If the 64 has a minus sign, then the solution is x = +/-5 Simplifying gives 4x squared = 100 ie x squared = 25...
10x2 - 64 = 36 + 6x2; whence, 4x2 - 100 = 0, x2 = 25, and x = ±5.
6x2+13x-5 = 0 (2x+5)(3x-1) = 0 x = -5/2 or x = 1/3
6x2 + 9x = 0 3x(2x + 3) = 0 3x = 0 or 2x + 3 = 0 x = 0 or x = -3/2
