Well, solve for 0 and you get X^2 + 5x-6=0
Now you can use the quadratic formula or just do reverse F.O.I.L - look up both.
If you practice enough, you don't even have to think about.
So you get (x-1)(x+6)= 0
or x=1, x=-6
enjoy. But really, practice and it becomes a piece of cake.
Try -1. x=1, x=-6
5x plus 3 does equal 3 plus 5x; commutative law.
x2 + 5x =6 x2+5x -6 = 0 (x+6)(x-1) = 0 x+ 6 = 0 x = -6 x-1 = 0 x = 1
That equation has no solution. There is no possible number that's equal to 18 more than itself.
x2 + 5x = 6Subtract 6 from both sides:x2 + 5x - 6 = 0Factor:(x + 6)(x - 1) = 0The first value:x + 6 = 0, so x = -6The second value: x - 1 = 0, so x = 1The possible values of x are -6 and 1.
Try -1. x=1, x=-6

What is the answer to 2x - 5x plus 6.3 equals -14.4?
x2 + 5x =6 x2+5x -6 = 0 (x+6)(x-1) = 0 x+ 6 = 0 x = -6 x-1 = 0 x = 1
If 3x + 5x = -8, what is x + 1? 3x + 5x = -8 8x = -8 x = -1 x + 1 = -1 + 1 = 0
That equation has no solution. There is no possible number that's equal to 18 more than itself.
x=6
x2 + 5x = 6Subtract 6 from both sides:x2 + 5x - 6 = 0Factor:(x + 6)(x - 1) = 0The first value:x + 6 = 0, so x = -6The second value: x - 1 = 0, so x = 1The possible values of x are -6 and 1.
8x-7 plus 2x equals 6 plus 5x plus 2?
Yes.
How do you add 2x plus 3y equals 18 in 5x-y equals 11
