Question

solve the equation by factoring:

n^2-36=0

how would i start this equation ?

Answer 1

are you sure it's not n^2 - 36

Answer 2

whoops. yeah thats right

Answer 3

(n-6) (n+6)
binomial rule

Answer 4

so you would use the difference of squares rule to factor

Answer 5

a^2 - b^2 = (a-b)(a+b)

Answer 6

so what you are saying is that the A value is n^2 and the B value is -36 ???

Answer 7

a^2 = n^2 ----> a = n

b^2 = 36 -----> b = 6

Answer 8

okay i see.
