Question

6x^2+5=7x i have to use quadratic formula to find exact solution?

Answer 1

first rewrite:
6x^2 -7x +5=0
now this is in the form:
ax^2 + bx +c = 0
where a = 6, b = -7 and c = 5
Now use the formula:
x1 = [ -b-sqrt(b^2-4ac) ]/ [2a]
x2 = [ -b+sqrt(b^2-4ac) ]/ [2a]

Answer 2

i don't understand the x1 = [ -b-sqrt(b^2-4ac) ]/ [2a]
x2 = [ -b+sqrt(b^2-4ac) ]/ [2a] part
:S

Answer 3

what is the answer?

Answer 4

x = -7 +- sqrt(-7^2-4*6*5)/(2*6)
x= -7 +- sqrt(-71)/12
x= -7 +- i sqrt(71)/12
