How do you solve 3x2 plus 10x equals 8 by factoring?
3x² + 10x = 8 Rewrite as: 3x² + 10x - 8 = 0 The only way to get 3x² is 3x and x (3x + -- ) (x + --) The factors of 8 are {1 2 4 8} so the answers must be a pair of them. With 4 factors, and a negative sign (the -8), there are only 8 ways this can be written: (3x + 1)(x - 8) = 3x² - 23x - 8 (3x + 2)(x - 4) = 3x² -10x - 8 (almost) (3x + 4 )(x - 2) = 3x² - 8x - 8 (3x + 8)(x - 1) = 3x² +5x - 8 (3x - 1)(x + 8) = 3x² +23x - 8 (3x - 2)(x + 4) = 3x² + 10x -8 ◄ Success! (3x - 4)(x + 2) = 3x² +2x - 8 (3x - 8)(x + 1) = 3x² -5x - 8 Trial and error, error, error, is the key to this kind of problem. Seeing the -10x early can point you to see that maybe changing the signs can work. ■
If 3x plus 8 equals 8 what is x?
3x + 8 = 8 Therefore, 3x = 0 x = 0/3 x = 0
When x equals 8 what is the answer for 3x-x?
3x - x = 3*8 - 8 = 24 - 8 = 16
3x equals 1x plus 8 what does x equal?
3x = x+8 so 3x-x = 8 hence 2x = 8 and so x = 4
If 3x-111 what is the value of x2x?
IF 3X-1=11, WHAT IS THE VALUE OF X 2 + X?
What is the combined term of 2x plus x?
2x+x2x = x+xso 2x+x isx+x+x = 3x
What is 3x - 1 11 what is the value of x 2 x?
-if3X-1=11,what is the value of X^2+X?
What is x2x-1 multiplied by x?

If 3x plus 8 equals 8 what is x?
3x + 8 = 8 Therefore, 3x = 0 x = 0/3 x = 0
3x plus 8 equals 20-3x what is x?
3x + x + 8 = 204x + 8 = 204x = 12x = 3
When x equals 8 what is the answer for 3x-x?
3x - x = 3*8 - 8 = 24 - 8 = 16
3x equals 1x plus 8 what does x equal?
3x = x+8 so 3x-x = 8 hence 2x = 8 and so x = 4
When x equals 8 what is the value of 3x-x?
If x equals 8, then 3x equals 24. 24-x would equal 16.
What is x in the equation 3x plus 8 equals 20?
3x + 8 = 20 3x = 20 - 8 3x = 12 3x = 12/3 x = 4
What is the solution of y x 4 y 3x 8?
If you mean: y = x+4 and y = 3x+8 then x = -2 and y = 2
