Solve by using the quadratic formula 18x2 1412Solutiongiven
Solve by using the quadratic formula:
1/8x2 - 1/4=1/2
Solution
given 1/8x2 - 1/4=1/2 => x2/8 +0x - 3/4 = 0
quadratic equation ax2+bx + c = 0, then x =[ -b+/-sqrt(b2-4ac)]/(2a)
then a=1/8,b=0,c=-3/4
x = [0+/-sqrt(0+3/8)]/(2*1/8)
= 4sqrt(3/8) and - 4sqrt(3/8)
x = 2sqrt(3/2), x = -2sqrt(3/2)
