Solution for (45-5x^2)/(x^2+2x-15) equation:


D( x )

x^2+2*x-15 = 0

x^2+2*x-15 = 0

x^2+2*x-15 = 0

x^2+2*x-15 = 0

DELTA = 2^2-(-15*1*4)

DELTA = 64

DELTA > 0

x = (64^(1/2)-2)/(1*2) or x = (-64^(1/2)-2)/(1*2)

x = 3 or x = -5

x in (-oo:-5) U (-5:3) U (3:+oo)

(45-(5*x^2))/(x^2+2*x-15) = 0

(45-5*x^2)/(x^2+2*x-15) = 0

x^2+2*x-15 = 0

x^2+2*x-15 = 0

DELTA = 2^2-(-15*1*4)

DELTA = 64

DELTA > 0

x = (64^(1/2)-2)/(1*2) or x = (-64^(1/2)-2)/(1*2)

x = 3 or x = -5

(x+5)*(x-3) = 0

(45-5*x^2)/((x+5)*(x-3)) = 0

-5*x^2 = -45 // : -5

x^2 = 9

x^2 = 9 // ^ 1/2

abs(x) = 3

x = 3 or x = -3

x in { 3}

x = -3
