Question

the value of alegebraic equation 3x²+6x for x=3

Answer 1

given equation is 3x²+6x

given the value of x is 3

now substitute the x value in the given equation

3(3)²+6(3)

3(9)+6(3)

27+19

46

therefore the value of given alegebraic equation 3x²+6x is 46

Answer 2

Answer:

if x = 3 then the value of the equation is

x square is 3×3 so, x square is 9

now multiply 9 by 3 , which is 27

now let's go to the second term 6x

6×3 is 18

now add these two to get an answer of 45
