Question

polynomial that
p(x) = 3(2x+20
find
find the zero
of p
(x)​

Answer 1

Step-by-step explanation:

when we take x = -10

3(2x + 20)

3[2(-10) + 20]

3[-20 + 20]

3[0]

3× 0

=0

Answer 2

Step-by-step explanation:

p(x)=0

now, 3(2x+20)=0

6x+60=0

6x= -60

x=-60÷6

x=-10

so, -10 is a zero of the polynomial 3(2x+20)
