Multiply the polynomials: 1. (a + 3)(a - 2) 2. (x2 + 4)(x2 - 4) 3. (x2 + 3x + 1)(x2 + x + 2)
use the distributive property \[a(b\pm c)=ab\pm ac\]
using this you take the first variable of the first and multiply it by the second parenthesis and same with the second variable/constant of the first \[a(a-2)+3(a-2)\]
what do you get when yo udo this?
So then i got: 2a-2a + 3a-6
But I dont think that is right lol
@Outkast3r09
everything but your first multiplication is correct \[a(a)\neq 2a\]
hint: when you have a number to a power you get this correct \[2^2=2*2\]
so \[a*a=?\]
uhhh 2 squared ???
@Outkast3r09
not quite so 2 is the base
in \[2^2\]
the power tells you how many times you multiply that base by itself
so \[2^3=2*2*2\] \[2^5=2*2*2*2*2\]
so in your case \[ a*a\] a is your base and the number of bases you multiply is your power
so \[a*a=a^2\]
I know how to do powers lol. I just dont know what \[a \times a\] is
oh okay lol
