That doesn't factor neatly. Applying the quadratic formula, we find two imaginary solutions: (1 plus or minus i times the square root of 69) divided by 7
x = 0.142857 repeating + 1.1866605518454392i
x = 0.142857 repeating - 1.1866605518454392i
where i is the square root of negative one.

How do you simplify 7x2 - 9x - 10?
I suppose you mean, how do you factor it. 7x2 - 9x - 10 = (7x + 5)(x - 2).

Do two plus signs make a minus?
NO!!!! Here is a table for multiplication/division of 'double (+/-) signs.'. (+)(+) = (+) (+)(-) = (-) (-)(+) = (-) (-)(-) = (+) Sometimes in higher level maths, you can have triple signs. Here is the table. (+)(+)(+) = (+)(+) = (+) (+)(-)(-) = (-)(+) = (-) (-)(+)(+) = (-)(+) = (-) (-)(-)(-) = (+)(-) = (-) It is irrelevant on the position of the 'sign'. NB If no sign is given, then read it as positive (+).
How do you factor 7x2-70?

Square root of a blonde minus cube of a brain plus factor of 20?
Your answer is either: 2, 4, 5, or 10. The square root of one blonde = 1. 1 minus the cube of one blonde brain = 0. 0 plus one factor of 20 (factors of 20 are: 2, 4, 5, 10) = which ever factor you choose. :)
How do you find a constant k such that x minus 2 is a factor of x4 minus 5x3 plus kx2 plus 3x minus 10?
