Hello from MrBillDoesMath!
Answer:
"The factoring should follow the perfect square trinomial pattern"
Discussion:
y^2 - 2(y)(3) + 3^2 =
(y -3
) ^2
not (y-3) (y+3) so the last step shown is incorrect. The answer is "The factoring should follow the perfect square trinomial pattern"
Thank you,
MrB
In integers subtraction and addition are almost same ....
Addition<span> :in addition if both numbers have different signs ..i.e - and + then we would find the difference and put the greater number sign ...For eg:(-6) + 12 =6 ...</span>
<span> if both are same ..i.e if both are either positive(+) or negative(-) then you add(or find the sum) and put the common sign ... For eg :+5+10 = +15 and (-5) + (-10) = (-5)]
Subtraction: in subtraction what you do is changing the sign of the second number ...and then depending upon the both signs follow the rules of addition ...
for eg: 6 - 4 ..it becomes 6 + (-4) ...so as they have different signs we can subtract them and put the greater number sign ...
i.e, 6 + (-4) = 2 ...
To find the sum follow these rules ......mentioned above ....
u can ask if you have any doubt ....
Hope it helps !!!</span>
