Question

solve by factoring: 4x^2-9=0

Answer 1

\[(2x)^2 - 3^2 = 0\]

Can you use the formula now???

Answer 2

what formula would i use?

Answer 3

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

Answer 4

\[(a^2 - b^2) = (a-b)(a+b)\]

Answer 5

is it (2x-3)(2x+3)=0

Answer 6

Yes dear, you are right..

Now put separately both the factors = 0

(2x - 3) = 0 and (2x + 3) = 0

and now find x from here..
