x2 + 8x = 3
Answer by stanbon(75887) (Show Source): You can put this solution on YOUR website!
x^2 + 8x = 3
---
x^2+8x-3 = 0
---
Formula: x = [-b +-sqrt(b^2-4ac]/[2a}
-------------------------------------------
a = 1 ; b = 8 ; c = -3
---
x = [-8 +- sqrt(64-4*1*-3)]/[2*1]
---
x = [-8 +- sqrt(76)]/2
---
x = [-8 +- 2sqrt(19)]/2
---
x = [-4 +- sqrt(19)]
x = -4+sqrt(19) or x = -4-sqrt(19)
====================================
