Question

math check please, trying to learn this

(√x-4 +3)^2 = x+3-4√x-4

Answer 1

\[(\sqrt{x-4}+3)^{2}??\]

Answer 2

yes, just trying to figure out this square system

Answer 3

really clueless...obviously lol

Answer 4

\[(\sqrt{x-4}+3)(\sqrt{x-4}+3)\]
FOIL
\[(x-4)+3\sqrt{x-4}+3\sqrt{x-4}+9\]

Answer 5

\[x+5+6\sqrt{x-4}\]

Answer 6

thank you...somehow that never occured to me...

Answer 7

If you dont understand why (x−4).
Example
\[\huge (\sqrt{x})(\sqrt{x})\]
\[\huge (x ^{\frac{1}{2}})(x ^{\frac{1}{2}})\]
\[\huge x ^{\frac{1}{2}+\frac{1}{2}}=x\]

Answer 8

just learned that.... just finished my last problem (that yo and others answered earlier) now trying to learn it...thank you very much
