Question

What is the zero of the linear polynomial, -9x + 15 which is the same as -3(3x - 5) ?
The zero of -9x + 15 =

Answer 1

Answer:

5/3

Step-by-step explanation:

-9x=-15

x=15/9

x= 5/3

Answer 2

Answer:

5/3

Step-by-step explanation:

In order to find zeroes of any polynomial, equate the expression to zero.

-9x + 15 = 0

Transpose -9x to Right hand side (RHS)

15 = 9x

(on transposing, the sign + changes to - and vice versa)

we can rewrite it as

9x = 15

X = 15/9

X = 5/3
