How do you factor negative two x squared plus 32?
-2x2+32 -2(x2-16) -2(x+4)(x-4)
What are the factors of x2-8x plus 16?
x^2 - 8x + 16 = 0(x )(x )You need two numbers that when multiplied are equal to 16, and when added are equal to 8.These two numbers are 4 and 4 (4 * 4 = 16, 4 + 4 = 16)Then you need to figure out if these are positive or negative. Since 16 is positive, you know that the numbers are either both positive or both negative. Since the 8 is negative, you know they must be negative.(x - 4)*(x - 4)
How do you solve y plus x divided by 2 equals negative 4 when x is 2?
First, solve for y.y=-8xif x=2, then y=-16.
What is 8 times negative 2?
-8 x -8 = +16anything which is minus x minus = plus (- x - = +)
What 2 numbers product is 16 and their sum is negative 10?
(-8) x (-2) = 16 (-8) + (-2) = -10 The two numbers are therefore -8 and -2.
What integer added to positive 16 equals negative 4 divided by positive 2?
X = integer X + 16 = - 4/2 X + 16 = - 2 X = - 18
What is 7 equals 2 plus x over negative 2?
x=-16
Negative 2 to the fourth power equals?
(-2)^4 = (-2)x(-2)x(-2)x(-2) = 16
When is a negative number raised to an odd power negative?
It is always negative when raised to an odd power and always positive when raised to an even power -2 to the third power = -2 x -2 x -2 = -8 -2 to the fourth power = -2 x -2 x -2 x -2 = +16
What does a positive number multiplied by a negative number equal?
A negative times a positive equals a negative. For example 2 x -16=-32 A negative times a negative equals a positive For example -2 x -16=32 A positive times a positive equals a positive For example 2 x 16=32 Remember that this rule only applies to multiplication and it doesn't matter if the smaller number has the negative sign or the bigger number has the negative sign; It will still be a negative. Also remember that it doesn't matter whether its a negative times a positive or a positive times a negative ; It remains a negative regardless of the order of the signs. Lastly remember that a negative times a negative will always be a positive and a positive times a positive will always be a positive. For example -2 x 105=-210 105 x -2=-210 2 x -105=-210 -105 x 2=-210 105 x 2 =210 -105 x -2 =210 So this means that a negative times a positive will always equal a negative, a negative times a negative will always equal a positive, and a positive times a positive will always equal a positive. Now if you were dealing with more than two numbers with both negative and positive signs, the easiest way to know whether the answer will come up as a negative or positive is to imagine two negative signs merging into a positive sign and any remaining negative sign that does have another negative sign to pair with remains a negative;You can only combine negative signs in pairs(for example -2 x -2 x -2=4 x -2=-8).Now if you have a situation where you were able to pair up all of the negative signs into positives signs and have no negative signs left over, then the answer will be a positive (for example -2 x -2 x -2 x -2 x 2=16 x 2=32).
What is x if negative 2 over 3 times x equals 5 over 8?
2/3 * x = 5/8 5/8 / 2/3 = x 5/8 * 3/2 = x 15/16 = x ^^ Above is all the work done to answer the following question. The answer was done correctly except that the negative 2 will yield an answer that is: - (15/16) = x

What is 8 times negative 2?
-8 x -8 = +16anything which is minus x minus = plus (- x - = +)
What 2 numbers product is 16 and their sum is negative 10?
(-8) x (-2) = 16 (-8) + (-2) = -10 The two numbers are therefore -8 and -2.
What is 2 times -4 plus 10?
a negative times a positive is a negative so 2*-4=-8+10=2
