1/2 = 3/6

1/3 = 2/6

How do i solve z^2+9=10z
Musya8 [376]

Answer:

z = 1, z = 9

Step-by-step explanation:

Given

z² + 9 = 10z ( subtract 10z from both sides )

z² - 10z + 9 = 0

Consider the factors of the constant term (+ 9) which sum to give the coefficient of the z- term (- 10)

The factors are - 1 and - 9, since

- 1 × - 9 = 9 and - 1 - 9 = - 10, thus

(z - 1)(z - 9) = 0 ← in factored form

Equate each factor to zero and solve for z

z - 1 = 0 ⇒ z = 1

z - 9 = 0 ⇒ z = 9

What does it mean for a product of factors to be expressed using exponents
leonid [27]
Product factor is an expression in where you multiply the same value digit SEVERAL times
Exponent is the expression in where you convert product factor expression into a more brief (shorter) expression
For example of product factor:
-> 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3
As you can see, 3 is multiplied many times, that makes it more extended.
Now, let’s make this product factor shorter using exponent.
-> since 3 is multiplied 3 times the exponent expression is:
-> 3 3 in where 3 is the base and the other 3 is called exponent.
