4X2 + 7X - 2 = 0

I am too lazy to use anything but the quadratic formula here!

X = - b (+/-) sqrt(b2 - 4ac)/2a

a = 4

b = 7

c = - 2

X = - 7 (+/-) sqrt[(72 - 4(4)(- 2)]/2(4)

X = - 7 (+/-) sqrt(49 + 32)/8

X = - 7 (+/-) sqrt(81)/8

X =[ - 7 (+/-) 9]/8

=====================so,

X = 1/4

=======and

X = - 2
