Answer:
(-3.028, 0) (.208, 0)
Step-by-step explanation:
You would plug in the quadratic equation or you would use a calculator to solve the following equation.
Factor out the GCF
15x^2+20x
15x^2/5x= 3x
20x/5x= 4
Final answer: 5x(3x+4)
Not sure what to tell you about this..
The solution for the #23 equation is either x=9 or x= -3
3/5/2 = 1/4/x
Cross multiply!
3/5/2 = 1/4/x
(3/5) * (x) = (1/4) * (2)
3/5x = 1/2
Multiply both sides by 5/3!
(5/3) * (3/5x) = (5/3) * (1/2)
x = 5/6
So, (3/4)/2 = (1/4)/x = 5/6.
