Yes and x = 2+square root of 6 or x = 2-square root of 6
X2 - 4X - 5 = 0 easy factor, what two factors of - 5 add up to - 4 (X + 1)(X - 5) X = - 1 ------------- X = 5 --------------
4x + 20
-4x-1-3x-4+5 = -7x-1-2x+1+6 -7x = -9x+6 2x = 6 x = 3
3x - 5x + 4x = -2x +4x = 2x
-4x-6x = -20 -10x = -20 Divide both sides by -10 rembering that a minus divided into a minus the result is positive: x = 2
4x2 - 9 = (2x + 3)(2x - 3)
i think its 10
16
4x2=8 8+22=30 You get 30 it really is simple
4x - 2x = 2x
Variables are just letters to solve for the unknowns. ex of a variable: 4x-6 = 16 x is a variable in this case, so we solve for it 4x = 22 x = 11/2
Yes and x = 2+square root of 6 or x = 2-square root of 6
How do you solve y=-4x+1
X2 - 4X - 5 = 0 easy factor, what two factors of - 5 add up to - 4 (X + 1)(X - 5) X = - 1 ------------- X = 5 --------------
Well, isn't that a happy little math problem? When you have 4x and take away 2x, you are left with 2x. It's just like painting a beautiful landscape - sometimes you have to simplify things to see the true beauty underneath.
