Quadratic Equations - Difference of Two Squares(L2)


Practice

Solve for x.
a)    0 = 4x2 −25
{-5/2,5/2}

b)    169 = 81x2
{-13/9,13/9}

c)    4x2 =121
{-11/2,11/2}

d)    0 = 49x2 −64
{-8/7,8/7}

e)    16x2 =9
{-3/4,3/4}

f)    16 = 25x2
{-4/5,4/5}

g)    49 = 81x2
{-7/9,7/9}

h)    36 = 25x2
{-6/5,6/5}

i)    121 = 36x2
{-11/6,11/6}

j)    0 = 25x2 −16
{-4/5,4/5}
