Quadratic Equations - Difference of Two Squares(L2)


Practice

Solve for x.
a)    0 = 9x2 −25
{-5/3,5/3}

b)    25 = 9x2
{-5/3,5/3}

c)    4 = 25x2
{-2/5,2/5}

d)    36 = 49x2
{-6/7,6/7}

e)    49x2 =25
{-5/7,5/7}

f)    144 = 25x2
{-12/5,12/5}

g)    9x2 =16
{-4/3,4/3}

h)    0 = 36x2 −49
{-7/6,7/6}

i)    9x2 =49
{-7/3,7/3}

j)    16 = 49x2
{-4/7,4/7}
