Practice

Solve for x.
a)    49x2 −100 = 0
{-10/7,10/7}

b)    16 = 49x2
{-4/7,4/7}

c)    49x2 =64
{-8/7,8/7}

d)    0 = 49x2 −64
{-8/7,8/7}

e)    64x2 −25 = 0
{-5/8,5/8}

f)    9 = 16x2
{-3/4,3/4}

g)    169 = 81x2
{-13/9,13/9}

h)    0 = 81x2 −4
{-2/9,2/9}

i)    64x2 −25 = 0
{-5/8,5/8}

j)    0 = 4x2 −121
{-11/2,11/2}
