How do i solve this, by factorizing...

Question

4x(squared)-196=0

Example: 3x(squared)-12=0
(3x+6)(x-2)

THNX

Answer 1

4x(squared)-196=0
4 (x^2-49) = 0
4(x-7)(x+7) = 0
that gives you the answer as x = 7 or x = -7 but if you want it in the rather unusual form you used for the example, multiply out the 4
(4x-28)(x+7) = 0

Answer 2

or (4x + 28)(x-7)
