1. what are the solutions to the equation 4b^2−45=−9

enter your answer with no spaces like the example provided here: x=2,-1

2. what are the zeros of the function represented by the quadratic expression
2x^2+x−3

3. simplify

−245−−√+33√+23√

4. 28√⋅20−−√

which of these is equivalent to this expression?

a. 3210−−√

b. 5

c. 810−−√

d. 228−−√

5. which product is irrational?

a. 2√⋅50−−√

b.10−−√⋅8√

c. 9√⋅49−−√

d. 64−−√⋅4√

 question 1: b=3 b=-3

b=3,-3

question 2: factor by grouping  (x−1)(2x+3)

zeros of a function represent the x value's' that result in the 'y' value being 0. Therefore the zeros of the function represent the 'x-intercept's', when the function is being graphed.

question 3&4: CANNOT BE SIMPLIFIED BECAUSE THE EQUATIONS GIVEN ARE  INCOMPLETE(comment the equation in the comment section )

question 5:  irrational numbers are  when There is no rational number whose square is 2.  Therefore we call radical an irrational number.  so that follows √5,√6,√7,√8,√2,√3

A) IS THE ANSWER ACCORDING TO THE STATEMENT

1: b=3 b=-3

2: group (x−1)(2x+3)

3:  -2/45+3/3+2/3

4: 2/8* /20

5: A.

Good luck!
