Question

if x = - 9 then form to valid equations For x

Answer 1

Answer:

x+9=0.

Step-by-step explanation:

transfer -9....which is their on the rhs side to lhs .

when it is transferred from rhs to lhs the sign will change from - to +.

therefore -9 is the root (or) zero of the x+9=0.

here the equation has only one zero because it is an linear polynomial with one degree .
