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?

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?

(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 = \(??\)

Last one. (x+3)(x+3)=x(x+3)(3(x+3)
x^2+6x+6
OpenStudy (koikkara):
\(last~term~wrong~!!\)

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