Confused at 10:52 so if you use 4 to multiply through the numerator you will get the same answer

[@SkanCityAcademy_SirJohn]

Yes, but eventually you will still need to divide by 4 to simplify the results

[@randomorange6807]

16:49 why does the denominator become negative?

[@SkanCityAcademy_SirJohn]

When rationalizing the denominator you multiply by the conjugate of the denominator, so if the original denominator is a+b, conjugate of (a+b) is a-b

[@reecewithoutherspoon1324]

at 21:55, why does 2 go into 6 to make 3?

[@SkanCityAcademy_SirJohn]

Two goes into 6, 3 times. Thus 2*3 = 6. That's correct

[@reecewithoutherspoon1324]

@@SkanCityAcademy_SirJohn But where did 2 originally come from?

[@reecewithoutherspoon1324]

@@SkanCityAcademy_SirJohn I get 2*3 = 6, but im having trouble understanding why 2 is the number we use to divide by

[@SkanCityAcademy_SirJohn]

Okay, so the numerator and the denominator are even hence are divisible by 2, since we need to reduce to the simplest form, we divided by two.

[@shashankshekhar6545]

Niche a²-b² lagega last question

[@i_am_roroo]

Conjugate of surds example 2,why didnt you multiply 4 by root 3 to give you 4root3. You only multiplied 4 with root 7.

[@SkanCityAcademy_SirJohn]

i didnt do that, 4 was cancelled out, so neither was 4 multiplied by root 7 or root 3

[@i_am_roroo]

@@SkanCityAcademy_SirJohn I kindly didnt mean the final answer i mean the solution up there u were supposed to multiply 4 with the conjugate of root 7 - root 3 based on your explanation. but you only multiply 4 by root 7 not 4 by root 3. which make the final answer incorrect

[@SkanCityAcademy_SirJohn]

Yes I get you. I multiplied it, just that I did not expand... So you realize the numerator was 4(root7 + root3) this means 4 multiplies everything. But in the last step, 4 was canceled Iut, leaving the expression in the bracket (root 7 + root 3) and that's correct
