The correct option about squaring the binomial is that B. The student is wrong. There is a missing term.
<h3>How to use binomial theorem?</h3>
We want to square a binomial and using pascal's triangle in binomial theorem, we know that; (x + a)² will follow the pattern;
1x²a⁰ + 2a¹x¹ + 1x⁰a²
Thus, we can say that the expression (x + 3)² will give us;
x² + 2(3x) + 9a²
= x² + 6x + a²
Thus, we can say that the correct option about squaring the binomial is that B. The student is wrong. There is a missing term.
Complete Question is;
A student is instructed to square a binomial, and gets the result shown. Choose the correct description of the student's work. (x + 3)² = x² + 9 Choose the correct answer below.
A. The student is wrong. You cannot square a binomial, only monomials.
B. The student is wrong. There is a missing term.
C. The student is correct. Each given term is squared.
D. The student is wrong. The student should add the threes instead of multiplying them.

3 hours and 33 Mins that is the answer
Let x represent the amount Betty invested at 15%. The (2x+237) is the amount Betty has invested at 13%. Her total earnings are ...
x*0.15 + (2x+237)*0.13 = 1688.03
0.41x + 30.81 = 1688.03
x = (1688.03 -30.81)/0.41 = 4042.00
Betty has $4042.00 invested at 15%.
Betty has $237 +2*4042 = $8321.00 invested at 13%.
Angle B corresponds to angle Y
