X2 - 3X - 4 = 0factored(X + 1)(X - 4)----------------X = - 1X = 4-------------------(- 1, 0) and (4, 0)================solution set of X interception points
3x - 5 = 48 So 3x = 53 and x = 53/3 = 17.66...
3x2 - 19x - 14 = 0 3x2 - 21x + 2x - 14 = 0 3x(x - 7) + 2(x - 7) = 0 (x - 7)(3x + 2) = 0 x - 7 = 0 or 3x + 2 = 0 x = 7 or x = -2/3
3x2-4x-15 = 0 (3x+5)(x-3) = 0 x = -5/3 or x = 3

{-1,7}
x=4 or x=-4
First you have to set up a proprtion. 45 over x equals x over 5. Then you get x squared equals 225(45*5). Finally you have to find the square root of 225 which is 15.
What is the solution set of 2x2 + x = 15
Yes. I assume you mean (x2 + y2) / (a2 + b2) = 1. Set all the variables to the same value - for example, all equal to one - and you have a valid solution.

The set is [ 16 ] .
'x' must be zero, so the solution set is [ 0 ].
x = 4
n=6
a = [ 0, 4 ]
x = { +6, -6 }
