Question 115014
{{{7(x-3)75x-14=525x^2-1575x-14}}}
Using the quadratic formula, you get
{{{x = (-b +- sqrt( b^2-4*a*c ))/(2*a) }}}
{{{x = (-(-1575) +- sqrt( 1575^2-4*525*(-14)))/(2*525) }}}
{{{x = (1575 +- sqrt( 2480625+29400))/(1050)}}}
{{{x = (1575 +- 1584.3)/(1050)}}}
{{{x = (1575 +- 1584.3)/(1050)}}}
Two solutions.
{{{x = (1575 + 1584.3)/(1050)}}}
{{{highlight(x=3.009)}}}
{{{x = (1575 - 1584.3)/(1050)}}}
{{{highlight(x=-.009)}}}
{{{ graph( 300, 200, -5, 5, -2000, 2000, 7*(x-3)*75*x-14) }}}
