Practice

Solve for x.
a)    25x2 −169 = 0
{-13/5,13/5}

b)    0 = 4x2 −9
{-3/2,3/2}

c)    0 = 9x2 −16
{-4/3,4/3}

d)    16x2 =81
{-9/4,9/4}

e)    16 = 25x2
{-4/5,4/5}

f)    225 = 16x2
{-15/4,15/4}

g)    0 = 16x2 −225
{-15/4,15/4}

h)    9x2 −25 = 0
{-5/3,5/3}

i)    9x2 −25 = 0
{-5/3,5/3}

j)    0 = 36x2 −49
{-7/6,7/6}
