Practice

Solve for x.
a)    9x2 =64
{-8/3,8/3}

b)    16 = 81x2
{-4/9,4/9}

c)    0 = 9x2 −25
{-5/3,5/3}

d)    0 = 81x2 −196
{-14/9,14/9}

e)    0 = 25x2 −9
{-3/5,3/5}

f)    169 = 81x2
{-13/9,13/9}

g)    49x2 =36
{-6/7,6/7}

h)    0 = 4x2 −49
{-7/2,7/2}

i)    81x2 =100
{-10/9,10/9}

j)    0 = 4x2 −49
{-7/2,7/2}
