Answer:

Solution given:

$(x + \frac{b}{2a} ) {}^{2}$

Since it is a form of (a+b)²

we have

(a+b)²=a²+2ab+b²

here

a=x

b=b/2a

now

substituting value

x²+2*x*b/2a+(b/2a)²

$\bold{\green{x²+\frac{bx}{a}+\frac{b²}{4a²}}}$

$\frac{35}{4}$ feet below the surface

adding the 2 quantities

3 $\frac{1}{2}$ + 5 $\frac{1}{4}$

= (3 + 5 ) + ( $\frac{1}{2}$ + $\frac{1}{4}$ )

= 8 + ( $\frac{2}{4}$ + $\frac{1}{4}$ )

= 8 + $\frac{3}{4}$ = 8 $\frac{3}{4}$ = $\frac{35}{4}$
