Thanks JustSaiyan

JustSaiyan:

I didn't do anything other than tag people who aren't online. :\

JustSaiyan:

If no one helps in around..... 20 minutes, I will try to help, okay?

Comerpickles:

Thanks for introducing me to them. You helped XD

MARC:

\(AE=CE\)

MARC:

\(x^2-8=2x\)

MARC:

solve for x using factorisation method

MARC:

\(x^2-2x-8=0\) \((x-4)(x+2)=0\)

MARC:

x=4(acceptable bcoz it's positive),-2(not acceptable bcoz length can't hv negative value)

MARC:

\(AC=AE+EC\)

MARC:

\(AC=x^2-8+2x\)

MARC:

\(Sub~x=4~into~the~eqn\)

MARC:

\(AC=4^2-8+2(4)\)

MARC:

\(AC=16-8+8\)

MARC:

\(AC=?\)
