The factors of the quadratic equation is (x + 1) and (x - 6)
Given,
The quadratic equation; -2x² + 10x + 12
We have to find the factors of this equation using quadratic formula;-
Quadratic formula;- 
Here,
a = -2, b = 10 and c = 12
Now,
= 
= 
= (-10±14) ÷ -4
Solve for,
- 10 + 14 / -4 = -4/4 = -1
That is, (x + 1)
Solve for,
- 10 - 14 / -4 = -24/-4 = 6
That is, (x - 6)
Therefore, the factors for the given quadratic equation is (x + 1) and (x - 6)

Answer:
Are there answer choices or do you have to type it in yourself?
Answer:
<u>252 square inches is the surface area of Josiah's cereal box.</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Height of the box = 11 inches
Length of the box = 8 inches
Width of the box = 2 inches
2. What is the surface area of Josiah's cereal box?
Let's recall the surface area of a rectangular prism:
Surface area = 2 (width * length + height * width + length * height)
Surface area = 2 (2 * 8 + 11 * 2 + 8 * 11)
Surface area = 2 (16 + 22 + 88)
Surface area = 2 * 126
<u>Surface area = 252 inches²</u>
-8+b2-(5+b2). Since the - is outside the paranthesis the signs inside change: -8+b2-5-b2. -8-5=-3, b2-b2=0. Your answer: -3 :)
