Type that into the Wolfram Alpha website. It's a maths website that will pretty much do anything to any maths function you require (e.g graph, factorise, integrate etc...) See related links for the website address - alternatively, Google "Wolfram Alpha" and it takes you straight there. Happy maths-ing!
No. 3x plus 2x = 5x. 3x multiplied by 2x = 6x²
If that was 2x^2 + 5x + 2, it would factor to (2x + 1)(x + 2)
If you mean: (2x+2)(5x-5) then it is equivalent to 10x^2 -10
(2x + 1)(x + 2)
5x * 2x = 10x^2
(2x + 3)(x + 1)
(x - 1)(5x + 7)
(2x-3)(x-1)
(2x + 1)(x + 2)
2x2 - 5x + 12 does not factor. 2x2 - 5x - 12 factors into (2x + 3)(x - 4) 2x2 + 5x - 12 factors into (2x - 3)(x + 4)
5x+2x=7x2x + 5x = 7x
2(5x + 3y)(2x + 5y)
