2x^2+34x-141

- MATH -
**jai**, Tuesday, October 26, 2010 at 9:47pmsince, it's not factorable, use qudratic formula:

x = [-b +- sqrt(b^2-4ac)]/(2a)

where a=2, b=34, c=-141

x = [-34 +- sqrt(1156-4*2*(-141)]/(2(2))

x = [-34 +- 2*sqrt(571)]/4

x = (1/2)(-17-sqrt(571)) ; and

x = (1/2)(-17+sqrt(571))

so there,, :)
