<h3>What is a quadratic equation?</h3>
A quadratic equation is an equation whose leading coefficient is of second degree also the equation has only one unknown while it has 3 unknown numbers. It is written in the form of ax²+bx+c.
The given quadratic equation can be matched with its solution as shown below,
2x² − 32 = 0 → x = √(32/2) → x = {-4, 4}
4x² − 100 = 0 → x = √(100/4) → x = {-5,5}
x² − 55 = 9 → x = √(9+55) → x = {-8,8}
x² − 140 = -19 → x = √(-19+140) → x = {-11,11}
2x² − 18 = 0 → x = √(18/2) → x = {-3, 3}

Answer:
2 x 10^-7
Step-by-step explanation:
Move the decimal point 'til it becomes a number that is less than 10 and more than 1 then count it.

Answer:
145 lb
Step-by-step explanation:
416 x 5(oz) = 2080
(Now to convert oz to lb)
2080 ÷ 16 = 130
The apples are 130 pounds, now to add the barrel's weight
130 + 15 = 145
Answer:
max is 25 there is no min
Step-by-step explanation:
max is 25 because when you do the table the highest y value their is it is 25 the min they are the same so there is no absolute min
Answer:
First is 
Second is 
Step-by-step explanation:
Open up equations and do FOIL method.
First equation:
(x + 2y)(x + 2y)
x^2 + 2xy + 2xy + 4y^2
Second equation:
(y + 2x)(y + 2x)
y^2 +2xy + 2xy + 4x^2
