Question

How do i use the quadratic formula to find solution to 4x^2 + 45x + 24 = 0 using the quadratic formula

Answer 1

Answer:

-0.56 or -10.67 (rounded to nearest hundredth)

Step-by-step explanation:

quadratic formula is (-b +/- √(b^2 - 4ac))/2a, so

$\frac{-45 +/- \sqrt{45^{2} - 4(4)(24)}}{2(4)}$

which equals

$\frac{-45 +/- 40.51 (rounded)}{8}$

when you simplify this, you should get

-0.56 or -10.67
