How to solve the quadratic equations by completing the square

The steps are explained below.

Step-by-step explanation:

we have to explain the completing the square method used to solve quadratic equation.

Following steps are used:

Let general quadratic equation  

Step 1: Divide all terms by a to make the coefficient of equals to 1.

Step 2: Move the constant term to the right side of the equation.

Step 3: Add and subtract the square of half of the coefficient of x.

Step 4: Complete the square on the left side of the equation and subtract the constant term from right side of equation.

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
