The value of 23 squared is 529
A square number or perfect square is an integer that is the square of an integer; in other words, it is the product of some integer with itself.
For example, the 3² is 3 × 3 i.e the product of the 3 by itself , which is 9
Similarly, the square of 23 is 23² which is the same as the 23 × 23
= 529
Therefore the square of 23 is 529. this means that 23² = 529 and the square root of 529 is 23.

Subtract 66 from both sides
2x^2+12x -66 = 66-66
2x^2+12x-66= 0
Use quadratic formula with a=2, b=12 , c= -66
x= −b±√b2−4ac2a
x=−(12)±√(12)2−4(2)(−66)2(2)x=−12±√6724x=−3+√42 or x=−3−√42Answer:x=−3+√42 or x=−3−√42
A researcher calculates the expected value for the number of girls in three births. He gets a result of 1.5. He then rounds the result to 2, saying that it is not possible to get 1.5 girls when three babies are born. Is this reasoning correct? Explain.
You could have a Quadratic with 2 distinct solution meaning you have 2 different X intercepts
2 roots means the discriminan is positive in other words
D>0
When the discriminan is 0, D=0 we have exactly one x-intercept.
Discriminan D=0
and finally, if the discriminan were negative
D=0
then there is no solution or root at all.

Answer:
The first pizza is 6 slices, so each slice is 1/6 of a pizza. The second pizza is 4 slices, so each slice is 1/4 of a pizza. If you were to take one slice of each, you would get 1/6 +1/4 slice, which would be 5/12 of a pizza, as opposed to if you took 2 slices of the first pizza, which would only be 4/12 of a pizza.
