@iGreen

OpenStudy (solomonzelman):

You keep asking the same question, but you don't want to learn. Do you space out every class ?

OpenStudy (anonymous):

Yep.

OpenStudy (anonymous):

Just trynna finish a dam test -_-

OpenStudy (anonymous):

@iGreen

OpenStudy (igreen):

I g2g, sorry.

OpenStudy (anonymous):

@Koikkara I don't get it -_-

OpenStudy (anonymous):

I get z^2-56 but that's not right.

OpenStudy (koikkara):

(a+b)(a-b)=a^2-b^2 ....Its the formula...

OpenStudy (anonymous):

(z+8)(z-7)=z^2-56^2?

OpenStudy (anonymous):

That's not even a choice...

OpenStudy (koikkara):

but in this case, u can apply the 1st formula, i just solved for you....have a look at your previous questions...

OpenStudy (koikkara):

(z+8)(z-7)= z(z-7)+8(z-7) = \(??\)

OpenStudy (anonymous):

z^2+15z-56?

OpenStudy (anonymous):

Right?

OpenStudy (koikkara):

nope..

OpenStudy (anonymous):

z^2+z-56

OpenStudy (anonymous):

:D?

OpenStudy (koikkara):

\(Excellent~!!\)

OpenStudy (anonymous):

Oh darn really? :DD Okay lemme try this one

OpenStudy (anonymous):

(x+1)(x+7)=x(x+1)+7(x+1) = x^2+7x+8

OpenStudy (anonymous):

No?

OpenStudy (koikkara):

\(check~Again~!!\)

OpenStudy (koikkara):

7x\8x = \(??\)

OpenStudy (anonymous):

x^2+8x+7?

OpenStudy (koikkara):

\(Try~with~Concentration~!!\)

OpenStudy (koikkara):

\(WoW~!!~Amazing~!!\)

OpenStudy (anonymous):

7x/8x=0.875x

OpenStudy (anonymous):

Oh the 8x one is right?

OpenStudy (koikkara):

\(Bingo~u~are~correct~!!\)

OpenStudy (koikkara):

\(yes\)

OpenStudy (anonymous):

Last one. (x+3)(x+3)=x(x+3)(3(x+3) x^2+6x+6

OpenStudy (koikkara):

\(last~term~wrong~!!\)

OpenStudy (anonymous):

+9?

OpenStudy (koikkara):

\(3*3=6?\)

OpenStudy (koikkara):

\(Retype~Full~equation~!!\)

OpenStudy (anonymous):

(x+3)(x+3)=x(x+3)(3(x+3)

OpenStudy (anonymous):

I had added my bad! So it's x^2+6x+9?

OpenStudy (koikkara):

\(Incredible~!!\)

OpenStudy (anonymous):

OMFGFGGSDKFGHSJKRG I MADE A 60 AK/SDJFHSDJKGB SCREW MATH

OpenStudy (koikkara):

\(If~You~practised~before~you~could~have~got~100/100~"\)

OpenStudy (anonymous):

Continue this lesson tomorrow? My ride's waiting.
