Question 48983
Factor {{{25x^2-70x+49}}}
{{{x = (-b +- sqrt( b^2-4*a*c ))/(2*a) }}} {Use the quadratic formula]

..
{{{x = (-(-70) +- sqrt( (-70)^2-(4)(25)(49) ))/((2)(25)) }}}[Plug-in the values]
.

{{{x = (+70) +- sqrt( ((49000 - 49000) ))/((50)))) }}}[Simplify]
.
{{{x = ((70) +- sqrt( (0) ))/((50)))) }}}
.
{{{x = ((70  ))/((50)))) }}} [Reduce]
.
x = 7/5
