If you mean how do you factor z2 + 50z + 49, since the coefficient of z2 is 1, you just have to figure out what two numbers when multiplied together give you 49 and when added together give you 50. That's obviously 49 and 1. So...
z2 + 50z + 49 = (z + 49)(z + 1)
5(16x^2 + y^2)
4z2
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.
The other factor is 1.
12n2 plus 8n?
7z + 6s + s = 7z + 7s This can then be factorised using 7 as the factor: 7z + 7s = 7(z + s)
7+7z 7=7*1 7z=7*z 7(1+z) is factored form
2(x - 3y + 7z)
7z+9 = 72 7z = 72-9 7z = 63 z = 9
(z - 6)(z - 6)
2z+9.75-7z=-5.15
Zx(3+4)= Zx7 = 7z the answer is 7z
3z2 + 45z + 42 = 3(z2 + 15z + 14) = 3(z + 1)(z + 14).
z2 + 9z + 18 = z2 + 6z + 3z + 18 = z(z+6) + 3(z+6) = (z+6)*(z+3)
its either (z2+ 9)(z - 2) , (z2+ 2)(z - 9) , or (z2- 9)(z - 2)
The answer to 2Z plus 9.75 subtract 7Z subtract equals 14.90. This is a math problem.
z = -2
