Question 2677
compare with ax^2+bx+c=0
a=4
b=3
c=-2
<br>
By formula,
{{{x = (-b +- sqrt( b^2-4*a*c ))/(2*a) }}}
<br>
{{x = (-3 +- sqrt( 3^2-4*4*-2 ))/(2*4) }}}
<br>
{{x = (-3 +- sqrt( 9+32 ))/(8) }}}
<br>
Root of (9+32) or (41) is: 6.4031 = 6.403
<br>
x=(-3+6.403)/8 AND (-3-6.403)/8
x=0.425375 AND -1.175375
<br>
<b>Solution set={0.425,-1.175}</b>
<P>
Hope this helps,
best of luck
