6x + 9 = -3 6x/3 + 9/3 = -3/3 2x + 3 = -1 2x + 3 - 3 = -1 - 3 2x = -4 2x/2 = -4/2 x = -2
6x-8+2x-5 = 7-2x 6x+2x+2x = 7+8+5 10x = 20 x = 20/10 x = 2
(3x-2)(2x+7) is the same as 6x^2 +17x -14 when the brackets are multiplied out
4x2 - 12x + 9 = 4x2 - 6x - 6x + 9 = 2x(2x - 3) - 3(2x - 3) = (2x - 3)(2x - 3) or (2x - 3)2
8x + 2 = 6x + 10 Subtract 6x from both sides: 2x + 2 = 10 Subtract 2 from both sides: 2x = 8 Divide by 2: x = 4 x = 4
8
(6x^5 + 12x) / (-2x^-3) =[ (6x^5 + 12x) (x^3) ] / (-2) =(6x^8 + 12x^4) / (-2)=(3x^8 + 6x^4) =(3x^4)[ (x^4) + 2 ]
(6x^3-9x^2) / (2x-3) = 3x^2((2x-3) / (2x-3) = 3 x ^2 (3 x squared)
2x times 3 is 6x because 2 multiplied by 3 is 6.2x times 3x would be 6x to the power 2 because 2x3=6 and x times x = xsquared
6x^2(2x + 5)
9+6x = 25-2x 6x+2x = 25-9 8x = 16 x = 2
2x + 9 = 6x + 1 9 - 1 = 6x - 2x 8 = 4x x = 2
x4+6x3-2x-12 (x3-2)(x+6)
8x^3 - 12x^2 + 6x - 9 = (8x^3 - 12x^2) + (6x - 9) = 4x^2(2x - 3) + 3(2x - 3) = (4x^2 + 3)(2x - 3)
(8x - 8) - (6x - 10) = ?8x - 8 - 6x + 10 = ?8x - 6x + 10 - 8 = ?2x + 2 = ?The answer is (2x + 2)
6x + 9 = -3 6x/3 + 9/3 = -3/3 2x + 3 = -1 2x + 3 - 3 = -1 - 3 2x = -4 2x/2 = -4/2 x = -2
6x-8+2x-5 = 7-2x 6x+2x+2x = 7+8+5 10x = 20 x = 20/10 x = 2
