What is the factor of 3z2-z-14?
(3z-7)(z+2)The way that I arrived at that is to find two numbers that made (3*14)=42 by multiplying and 1 by subtraction. The outside product is 6 and the inside product is -7.
What is the expression 3z2-16z-35 completely factored?
(3z + 5)(z -7)
The length of a rectangle is ten ft less than three times its width find the dimensions if the area is forty eight?
let the width be z so length is (3z-10) Area=length x width Area=48 z(3z-10)=48 3z2-10z-48=0 3z2-18z+8z-48=0 3z(z-6)+8(z-6)=0 (3z+8)(z-6)=0 z= - (8/3) which is not possible since dimensions can not be negative So z=6 Width=6 length=3x6-10=8 Dimension= 6 ft x 8 ft
What is the factorization of 20y2-11yz-3z2?
20y2 - 11yz - 3z2 = 20y2 + 4yz - 15yz - 3z2 = 4y(5y + z) - 3z(5y + z) = (4y - 3z)(5y + z)
How do you factor the trinomial 3z2 plus 45z plus 42?
3z2 + 45z + 42 = 3(z2 + 15z + 14) = 3(z + 1)(z + 14).

What is the expression 3z2-16z-35 completely factored?
(3z + 5)(z -7)
What is the GCF ofz3-3z2?
The greatest common factor (GCF) refers to a factor that is COMMON to two or more numbers or expressions. You have only one expression in the question! The greatest factor of any number is itself.

What formula is used for the resultant field of a magnetic material?
First off, this needs to be expressed in cylindrical coordinates, ρ, φ, and z, so as to not drive me crazy. By doing this, the magnitude of the resultant magnetic field from a magnetic material becomes φ independent and is expressed by: B = {μ0m/[4π(z2 + ρ2)3/2]}{√[1 + 3z2/(z2 + ρ2)]}, where μ0 is the permeability of free space and m is the dipole moment.
