-2x^2+50x+40=0
-2*(x^2-25x-20)=0
x^2-25x-20=0
complete square:
x^2-25x-20+156.25^2=0+156.25
x^2-25x+156.25^2=20+156.25
(x-12.5)^2=176.25
x-12.5=+/-sqrt(176.5)
x=12.5+/-sqrt(176.5)

Step-by-step explanation:
Answer:
The answer is 30240
Step-by-step explanation:
Answer:
No x-intercept/Zero
Step-by-step explanation:
f(x)=3x(3/4)x-4
To find x-intercept/zero, substitute f(x)=0
0=3x(3/4)x-4
To raise a fraction to a power, raise the numerator and denominator to that power
0=3x 3 x-4/4 x-4
Calculate the product
0=3 x-3/4 x-4
Since the right-hand side is always positive, the statement is false for any value of x
Since there is no solution for f(x)=0, there is no x-intercept/Zero
