Question

if p(x) 3x²+5x-7 then find p(1) ​

Answer 1

Answer:

3(1)^2+5(1)-7=0

3x^2+5-7=0

3x^2-2=0

x^2=-2/3

Answer 2

Answer:

p(1) = 1

Step-by-step explanation:

given that p(x) = 3x²+5x-7

to find p(1), just we have to substitute the x value as 1 in the above equation.

ie., p(1) = 3 (1²) + 5(1)-7

           = 3+5--7

           = 8-7

           = 1
