Question

Extracting 3h^2-147=0 answer and solution pls...

Answer 1

3h² - 147 = 0

3 × ( h² - 49 ) = 0

h² - 49 = 0

Now, if you are sudden spontaneous and will not forget that any square can have two answers then do this,

h² = 49

h = ± 7

Otherwise,

h² - ( 7)² = 0

( h + 7 )( h - 7 ) = 0

h + 7 = 0 or. h - 7 =0

h = -7 or h = 7

So, h = -7 , 7

h = ±7
