Question 2677: 4x^2 + 3x -2=0

You can put this solution on YOUR website!
compare with ax^2+bx+c=0
a=4
b=3
c=-2


By formula,
x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+


{{x = (-3 +- sqrt( 3^2-4*4*-2 ))/(2*4) }}}


{{x = (-3 +- sqrt( 9+32 ))/(8) }}}


Root of (9+32) or (41) is: 6.4031 = 6.403


x=(-3+6.403)/8 AND (-3-6.403)/8
x=0.425375 AND -1.175375


Solution set={0.425,-1.175}


Hope this helps,
best of luck
