Answer:
The correct option is;
B. The difference of 2 perfect squares
Step-by-step explanation:
Solving a quadratic equation using factoring involves finding the factors of the equation that would yield the result of the quadratic equation
In order to find the roots of the quadratic equation, then the result of the factoring must be equal to zero, in which case, the constant terms in the factors are the solutions of the quadratic equation in opposite sign.
For example, we have;
x² - 5² = 11
We subtract 11 from both sides to get;
x² - 5² - 11 = 11 - 11
x² - 36 = 0
x² - 6² = 0
(x - 6) × (x + 6) = 0
Therefore, x = 6 or -6 which are the opposite sign of the constant terms in the factor.
It might be 3/4, 6/5, 9/6, 12/7, 15/8
Answer:
m=52.17
Step-by-step explanation:
<em>The complete question in Spanish is</em>
El área de la región rectangular es 4400 cm2. Calcular el valor de m
largo :2m-20
ancho: m
<em>The question in English is</em>
The area of the rectangular region is 4400 cm2. Calculate the value of m
length :2m-20
width: m
we know that
The area of a rectangle is equal to
where
L is the length
W is the width
we have
substitute in the formula the given values and solve for m
Distribute in the right side
Solve the quadratic equation by graphing
Using a graphing tool
The solution is m=52.17 (the positive value is the solution)
see the attached figure
Hi!
-9f + 19 - 1 + f is actually -8f + 18.
To do this we add like terms, -9f and f; and 19 and -1
-9f + f is -8f
19 - 1 is 18
Therefore your answer is -8f + 18
