16x - 8x + 12 = 78 + 22

or simplified to (16x-8x=8x)(78+22=100)

8x + 12 = 100

Simplify some more (Subtract 12 from both sides)

8x = 88

Divide both sides by 8, and x = 11

16x+9 without the rest of the equation, what this equals, I can't solve

If your function is 4x^2+16x+16=0 then x=-2, if it is 4x^2-16x+16=0, then x=2

(the shape is an upside down 'u').

(x+8)^2=105

8x2 + 16x + 8 = 0

You can't solve it. But you can simplify it to get: 4x+y=2

16x + 2 - 8 = 16x + 24 implies 16x - 6 = 16x + 24 subtracting 16x from both sides, this implies: -6 = 24 So the equation has no soultions.

Assuming you wish to make this equation equal zero, for x2 + 16x + 55 = 0, x = -5.

a=64 b=8 (x+16x+64)=(x+8)^2

In order to solve that equation, you need to get your X's on one side and your numbers on the other. First, you subtract 2X from both sides to get -10= -2 +16X. Then, you add 2 to both sides to get -8=16X. Finally, you divide both sides by 16 to get the X by itself to get X=-.5.

That won't factor neatly, so we apply the quadratic formula. x = -8 plus or minus 2 times the square root of 5 x = -3.5278640450004204 x = -12.47213595499958

8-8x=8x+18 Through simple algebra, this can be manipulated to solve for x: 8=16x+18 -10=16x -5/8=x

16x-8x+12 = 78+22 16x-8x = 78+22-12 8x = 88 x = 11
