Solve 5x 2 - 7x + 2 = 0 by completing the square. what are the solutions?

or

Step-by-step explanation:

The given quadratic equation is

Group the constant terms on the right hand side.

Divide through by 5.

Add the square of half the coefficient of x., which is to both sides of the equation.

The left hand side is now a perfect square.

Take the square root of both sides;

or

or

or

Step-by-step explanation:

- You must divide the equation by 5:

- Add and subtract :

Therefore, you obtain:

-add 0.09} to both sides:

- Apply square root to both sides and solve for x:

$450.00 for 6 weeks

or

$300

step-by-step explanation:

$200.00 for first week $50.00 x5 equals $250 plus $200 equals $450.00 for six weeks.

$200 for first week

$200 x 0.10 = $20

$20 x 5 = $100

$200 + $100 = $300

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
