we have

3x^{2} -8x+5

Equate the expression to zero to find the roots

3x^{2} -8x+5=0

Group terms that contain the same variable, and move the constant to the opposite side of the equation

3x^{2} -8x=-5

Factor the leading coefficient

3(x^{2} -(8x/3))=-5

Complete the square. Remember to balance the equation by adding the same constants to each side.

3(x^{2} -(8x/3)+(16/9))=-5+(16/3)

3(x^{2} -(8x/3)+(16/9))=(1/3)

Rewrite as perfect squares

3(x-(4x/3))^{2}=(1/3)

(x-(4x/3))^{2}=(1/9)

square roots both sides

(x-\frac{4}{3})=(+/-) \sqrt{\frac{1}{9}}

x=\frac{4}{3}(+/-) \frac{1}{3}

the roots are

x=\frac{4}{3}+ \frac{1}{3}=\frac{5}{3}

x=\frac{4}{3}- \frac{1}{3}=\frac{3}{3}=1

so

3x^{2} -8x+5=3(x-\frac{5}{3})(x-1)=(3x-5)(x-1)

therefore

<u>the answer is the option</u>

(3x-5)(x-1)

If sea water contains 3.5% of salt. How much seawater do you need in order to get 17.5 lb of salt?
CaHeK987 [17]

Answer:

500 lb

Step-by-step explanation:

Let x lb be the weight of seawater needed to get 17.5 lb of salt.

Now,

x lb - 100%

17.5 lb - 3.5%

Write a proportion:

\dfrac{x}{17.5}=\dfrac{100}{3.5}

Cross multiply:

x\cdot 3.5=100\cdot 17.5\\ \\x=\dfrac{100\cdot 17.5}{3.5}=500\ lb
