D( x )
4*x^2-x-24 = 0
7*c^2-(7*c)-36 = 0
4*x^2-x-24 = 0
4*x^2-x-24 = 0
4*x^2-x-24 = 0
DELTA = (-1)^2-(-24*4*4)
DELTA = 385
DELTA > 0
x = (385^(1/2)+1)/(2*4) or x = (1-385^(1/2))/(2*4)
x = (385^(1/2)+1)/8 or x = (1-385^(1/2))/8
7*c^2-(7*c)-36 = 0
7*c^2-(7*c)-36 = 0
7*c^2-7*c-36 = 0
7*c^2-7*c-36 = 0
x należy do R
x belongs to the empty set
4/(4*x^2-x-24) = 7/(7*c^2-(7*c)-36)
x belongs to the empty set
