Final answer:
The two solutions to the given equation are x = 0.0216 and x = -0.0224.
Step-by-step explanation:
The given equation -45ˣ⁴-69ˣ³+84ˣ²+60x-48=0 can be rearranged into a quadratic equation that equals 0:
x² - 0.0211x + 0.0211 = 0
We can now use the quadratic formula to solve for the two possible values of x:
x = 0.0216 or x = -0.0224
