3x - 24x + 5 + 3 = -21x + 8

It is a quadratic expression in the variable x.
5x^2-24x+11
3/(x2+4x-1) = 6/(2x2-3x+5) Cross - multiply in order to eliminate the fractions: 6*(x2+4x-1) = 3*(2x2-3x+5) 6x2+24x-6 = 6x2-9x+15 6x2-6x2+24x+9x = 15+6 33x = 21 x = 21/33 => x = 7/11
3x - 24x + 5 + 3 = -21x + 8

(3x - 8)(8x + 5)
It is a quadratic expression in the variable x.
There are two ways to solve this, by factoring or the quadratic formula. I recommend factoring if possible because it is faster. -18x2 + 24x + 10 = 0 The first thing I see, is that I should factor out a -2 to make this problem more workable. -2(9x2 - 12x - 5) = 0 The -2 is now irrelevant, so I can cancel it and factor what remains. (3x + 1)(3x - 5) = 0 Now solve each separate equation for x to get two answers. 3x + 1 = 0, 3x = -1, x = -1/3 3x - 5 = 0, 3x = 5, x = 5/3 ANS: x= -1/3, 5/3
No they are not the same.For example, for x =1: 24x3 -5x = 72-5 = 67 while 3x3 = 27
5x^2-24x+11
24x^5 + 24x^3 = 24x^3(x^2 + 1)
3x^5 If these are 5 of 3x multiplied together the it must be (3x)^5 =3^5 times x^5
3/(x2+4x-1) = 6/(2x2-3x+5) Cross - multiply in order to eliminate the fractions: 6*(x2+4x-1) = 3*(2x2-3x+5) 6x2+24x-6 = 6x2-9x+15 6x2-6x2+24x+9x = 15+6 33x = 21 x = 21/33 => x = 7/11
3x-5=3x+5 There is no solution.
