Answer:
Explanation:
For the equation 16x³ + 16x² + 3x = 0, we can factor out x:
x(16x² + 16x + 3) = 0
Using the quadratic formula, we can solve for the roots of 16x² + 16x + 3:
x = (-16 ± √(16² - 4(16)(3))) / (2(16))
x = (-16 ± √160) / 32
x = (-1 ± √10) / 4
So the solutions to the equation are x = 0 and x = (-1 ± √10) / 4.
For the equation 4x^2 - 9 = 0:
We can first add 9 to both sides:
4x^2 = 9
Then divide both sides by 4:
x^2 = 9/4
Finally, take the square root of both
