z+3 simplified as much as possible
In algebra we consider x,y and z are variables.
Algebra
Z2 - 5Z + 4 = 0 (Z- 1)(Z - 4) so, Z = 1 ---------- and Z = 4 -----------
y(z+x) + 4(x+z)
z+3 simplified as much as possible
If you know the values of ' y ' and ' z ', then the answer is the same no matter where you are.
It is an algebra expression meaning: 5n+4
In algebra we consider x,y and z are variables.
Algebra
6z-4z-z = 6-7-4 z = -5
In algebra z is a variable. What z equals would depend on the math problem you're doing and what the answer to that problem is.
It is a linear equation in the variable z.
Z2 - 5Z + 4 = 0 (Z- 1)(Z - 4) so, Z = 1 ---------- and Z = 4 -----------
y(z+x) + 4(x+z)

To find the multiplicative inverse of a complex number z = (a + bi), divide its complex conjugate z* = (a - bi) by z* multiplied by z (and simplify): z = 4 + i z* = 4 - i multiplicative inverse of z: z* / (z*z) = (4 - i) / ((4 - i)(4 + i) = (4 - i) / (16 + 1) = (4- i) / 17 = 1/17 (4 - i)
