Question

algebra!

Answer 1

√x+6−4=x
√x+2=x
Step 1: Add -2 to both sides.
√x+2+−2=x+−2
√x=x−2
Step 2: Solve Square Root.
√x=x−2
x=(x−2)2(Square both sides)
x=x2−4x+4
x−(x2−4x+4)=x2−4x+4−(x2−4x+4)(Subtract x^2-4x+4 from both sides)
−x2+5x−4=0
(−x+1)(x−4)=0(Factor left side of equation)
−x+1=0 or x−4=0(Set factors equal to 0)
x=1 or x=4
Check answers. (Plug them in to make sure they work.)
x=1(Doesn't work in original equation)
x=4(Works in original equation)

Answer 2

Yes

Answer 3

Its saying to solve for X right?

Answer 4

huh ? :/

Answer 5

Let's solve your equation step-by-step.
√x+6−4=x
Step 1: Add 4 to both sides.
√x+6−4+4=x+4
√x+6=x+4
Step 2: Solve Square Root.
√x+6=x+4
x+6=(x+4)2(Square both sides)
x+6=x2+8x+16
x+6−(x2+8x+16)=x2+8x+16−(x2+8x+16)(Subtract x^2+8x+16 from both sides)
−x2−7x−10=0
(−x−2)(x+5)=0(Factor left side of equation)
−x−2=0 or x+5=0(Set factors equal to 0)
x=−2 or x=−5
Check answers. (Plug them in to make sure they work.)
x=−2(Works in original equation)
x=−5(Doesn't work in original equation)
Answer:
x=−2

You get this

Answer 7

Its still one solution i dont know why you have an X and Y value
