Answer:
y² + y + = (y +
)²
Step-by-step explanation:
In most cases, we can factor a polynomial, or quadratic, by looking at the factors of the last term. In this case, the last term is . When we factor a polynomial, we are looking for two expressions that when multiplied together using FOIL (forward-outside-inside-last) will give us the polynomial. For example: (a + b)(a + b) or (a+ b)².
In order to get y² + y + , we are looking for a 'c' value that will add up to '1' which is our 'b' value (ay² + by + c).
Since
Then, we can use as our factor for both expressions. Putting this together we get: (y +
)(y +
) or (y +
)²
The step 7 is a wrong step, because in the denominator 1 is written in place of 2.
<h3>What is a quadratic equation?</h3>The quadratic equation is given as ax² + bx + c = 0. Then the degree of the equation will be 2. Then we have
Two of the steps in the derivation of the quadratic formula are shown below.
