2x squared - 5x - 3 = (2x +1)(x -3)
2x squared minus 5x minus 3 factored is (2x+1)(x-3).
6x2 + 5x - 6 is factored out to (2x + 3)(3x - 2).
2x2 + 5x + 3 Notice the first term, which can be rewritten as 2x times x. With this in mind, you can write the equation as...(2x + a)(x + b)...where -a and -b are the answers.You know that a times b is equal to 3.With a little trial and error, you will find:2x2 + 5x + 3 = (2x + 3)(x + 1)
(5x-10)(x+3)
Factorise: 5x2 + 2x - 192 = (x - 6)(5x + 32) = 0; whence, x = 6 or -6.4.
When you subtract 7x^2 from 5x^2, you get -2x^2.
(2x - 7)(x + 1)
2x squared - 5x - 3 = (2x +1)(x -3)
5
-x2+2x
2x squared minus 5x minus 3 factored is (2x+1)(x-3).
2x2 + 5x = x*(2x + 5)
What is the answer to 2x - 5x plus 6.3 equals -14.4?
x2 + 2x - 15 = 0(x + 5) (x - 3) = 0x = -5x = +3
(2x - 7)(5x + 9) ie x = 3.5 or -1.8
(5x 2 - 8x + 1) + (2x 2 - 4x - 11)
