Now use the distributive property to factor the expression you obtained in part D??????

Step2247 [10]

Answer:

150 + 2x

The greatest common factor of 150 and 2x is 2. Factor out a 2 from both terms:

2(75) + 2(x).

Use the Distributive Property, A(B + C) = AB + AC, to rewrite the expression:

2(75 + x).

The expression 150 + 2x is equivalent to 2(75 + x).

The first three steps for solving the quadratic equation by completing the square are shown. Fill in the missing number in the l

Oksi-84 [34.3K]

The first three steps for solving the quadratic equation by completing the square are as follows;

1. $\rm 9x^2 +54x = 7$

2. $\rm 9(x^2 + 6x) = 7$

3. $\rm 9(x^2 + 6x + 9) = 7 + 81$

Given

The quadratic equation given as 9x^2 + 54x = 7.

<h3>Quadratic equation;</h3>

The highest power of the degree is 2 is known as a quadratic equation.

To solve using the completing the square method.

The first three steps for solving the quadratic equation by completing the square are given below.

1. Write the equation in a way that the constants are on the right side while the terms with x are on the left.

$\rm 9x^2 +54x = 7$

2. Make sure that the coefficient of the x^2 term is 1.

$\rm 9(x^2 + 6x) = 7$

3. Adding a term to both sides that will complete the square on the left side.

This is done by dividing the coefficient of the x term by 2 and squaring it.

The same amount should be added to the right side to balance the equation.

$\rm 9(x^2 + 6x + 9) = 7 + 81$
