Answer:

Factoring is a step taken towards solving a quadratic equation. ... You cannot factor them, the only way to find the roots then, is by using the quadratic formula. Suppose you factor the quadratic polynomial as and . Then set them equal to zero and solve for , you will have

Step-by-step explanation.

Example 1 – Solve: x2 + 16 = 10x

Step 1: Write the equation in the correct form. In this case, we need to set the equation equal to zero with the terms written in descending order.

Step 2: Use a factoring strategies to factor the problem.

Step 3: Use the Zero Product Property and set each factor containing a variable equal to zero.

Step 4: Solve each factor that was set equal to zero by getting the x on one side and the answer on the other side.

The perimeter of a triangle equals 8 inches. Two of its sides are equal and each of them is 1.3 inches bigger than the third sid

mafiozo [28]

Let's call the lengths of our two types of sides <em /> $x$ and $y$ .

The two sides will that our 1.3 inches bigger than the third side will be have length x, and the length of the other side will be known as y. Thus, $x = y + 1.3$ .

Considering this, we can add our sides together and set this value equal to 8, given the information in the problem:
$(y + 1.3) + (y + 1.3) + y = 3y + 2.6 = 8$

Now, let's solve for y.
$3y + 2.6 = 8$
$3y = 5.4$
$y = 1.8$

Now, we are not done yet. We must determine the true lengths of all of our sides. Using the equation we found earlier, the length of the two bigger sides is $y + 1.3 = 1.8 + 1.3 = \boxed{3.1}$ inches and the length of our smaller side is simply $\boxed{1.8}$ inches.

To verify, we can add these sides together and check that they equal 8:
3.1 + 3.1 + 1.8 = 8 ✔
