Question

What are the solutions of the quadratic equation below? 4x2 - 30x + 45 = 0

Answer 1

Answer:

Solutions are x = 6.46 and 1.04

Step-by-step explanation:

The given quadratic equation is 4x² - 30x + 45 = 0

We have to find the solutions of the equation.

Now we will use the formula of quadratic equations

$x=\frac{30\pm \sqrt{900-16\times 45}}{8}$

$=\frac{30\pm \sqrt{500}}{8}$

$=\frac{30\pm 22.36}{8}$

$x=6.46$

Or $x=1.04$

Answer 2

You would solve for x by finding a, b, and c of the quadratic the you would use the quadratic formula. You should get x=$\frac{15+-3 \sqrt{5} }{4}$ and x~ 5.427
