Help me find roots by factoring?!

49x^2 = 28x - 4

Please help me :(!!!

49x^2 = 28x - 4

Please help me :(!!!

quadratic equation...set equal to zero...

49x^2 - 28x + 4 = 0

perfect square trinomial...

(7x - 2)^2 = 0

x = 2/7 (double root)

check

(a - b)^2 = a^2 - 2ab + b^2

qed

49x^2 - 28x + 4 = 0
(7x - 2)^2 = 0
x = 2/7
