Solve the following equations 5^2x-2(5^x)-15=0

castortr0y [4]

Answer:

x = 1

Step-by-step explanation:

${5}^{2x} - 2( {5}^{x} ) - 15 = 0$

$( {5}^{x} {)}^{2} - 2 \times {5}^{x} - 15 = 0$

${t}^{2} - 2t - 15 = 0$

${5}^{x} t = - 3 \: \: .5$

${5}^{x} = 5$

$x = 1$

Find the discriminant of the following quadratic equation then state the number of rational, irrational, and imaginary solutions

lianna [129]

Answer:

-6x² - 6 = -7x - 9
-6x² + 7x - 6 + 9 = 0
-6x² + 7x + 3 = 0
6x² - 7x - 3 = 0

Discriminant:

D = (-7)² - 4*6*(-3) = 49 + 72 = 121

Since D > 0, there are 2 real solutions:

x = (- (-7) ±√121 )/12
x = (7 ± 11)/12
x = 1.5, x = -1/3
