It is: 100x^2 -9 = (10x-3)(10x+3) when factored
6x2 + 10x = 2x*(3x + 5)
Are you seeking the factors? 7x2 - 10x + 3 = (x - 1)(7x - 3).
-3.
Assuming x(2-10x)=21 to be solved for x, distribute to -10x2+2x=21, or 10x2-2x+21=0. By the quadratic equation, we can determine there are no real solutions because the square root of -836 does not exist. In imaginary solutions, we can reduce to 1/10*(1 + sqrt(-209)) and 1/10*(1-sqrt(-209)) as solutions.
Equation: 10x^2 -29x +10 = 0 When factored: (2x-5)(5x-2) = 0 Its solutions: x = 5/2 or x = 2/5

The GCF is 10x.
(10x-3(10x+3)
x2 + 9x2 = 10x2

It is: 100x^2 -9 = (10x-3)(10x+3) when factored
multiply by 2y/x
( x^2 + 10x )^2 = ( x^2 + 10 x) ( x^2 + 10x ) = x^4 + 10x^3 + 10x^3 + 100x^2 = x^4 + 20x^3 + 100x^2 <----------------
6x2 + 10x = 2x*(3x + 5)
