You need to find two factors of 5*672 = 3360, whoxe difference is 4: these are 56 and 60.
Then 5x2 - 4x - 672 = 5x2 - 60x + 56x - 672 = 5x(x - 12) + 56(x - 12)
= (x - 12)*(5x + 56)

Need expression for X plus 10 and 5x?
Expression: x+10+5x Solve: x+5x=6x Answer: 6x+10
How do you solve 5x minus 30?
5x=30...then x=30/5. So X=6.
How do you solve this equation x equals one half x subtract 4?
x = .5x - 4. Get all of the x's on one side: x - .5x = .5x - .5x -4 ---> .5x = -4 Multiply each side by 2. x = -8
