Solve 9x^2 + 12x – 24 = 0 using the quadratic formula.
Nataliya [291]
Quadratic formula = (-b +- sqrt(b^2 - (4ac))) / 2a

\frac{ -12 +  \sqrt{(12)^2 -((4)(9)(-24))}}{2(9)}

and

\frac{ -12 - \sqrt{(12)^2 -((4)(9)(-24))}}{2(9)}

then simplify and solve

X^2-3x=7/4 <br> Solve by completing the square
padilas [110]

Answer:

Step-by-step explanation:

X^2-3x=7/4 should first be rewritten in standard form, which here would be:

x^2 - 3x - 7/4 = 0.

1.  Identify the coefficient of the x term and take half of that number:

    -3/2

2. square this result:  (-3/2)^2 = 9/4

3.  add this last result, 9/4, between the -3x term and the -7/4 term, and then      subtract it as shown:

     x^2 - 3x + 9/4 - 9/4 - 7/4 = 0

4.  Rewriting the first 3 terms as the square of a binomial, we get:

    (x - 3/2)^2  -  16/4 = 0, or    (x - 3/2)^2  =  16/4

5.  Take the square root of both sides, obtaining:

     x - 3/2 = ±√4/2 or ±√2

6.  Write out the two roots:  x = 3/2 + √2

     and                                   x = 3/2 - √2

16% of what number is 17?
kirill [66]
To find a percentage of a number, convert the percent to a decimal, then multiply the number by it. In this case, 16% = 0.16.

N * 0.16 = 17
N = 106.25
