x^4-5x^2-36=0
factor
(x^2-9)(x^2+4)=0
split into 2 equations because one of these terms will need to equal zero for the eqation to be true
x^2-9=0 x^2+4=0
x^2=9 x^2=-4
x=+/-3 no real numbers

Answer:
75% of the votes were in favor.
Step-by-step explanation:
To find the percent(rate), we use the formula r=p/b
The question is "What percent(rate) of 56 is 42?"
So fill in the formula and it will show as r=42/56, which is the rate will be equal to 42 divided by 56.
Perform the calculations and the result will show 0.75
Convert the decimal to a percent by moving the decimal point two places to the right and you will have 75% as your answer.
