2x3 - 3x2 + 4x + 5 with x = 4.
Since we know what " x " equal , we can plug it into the equation
By plugging it into the equation , you would get
2(4)^3 - 3(4)^2 + 4(4) + 4 ok , now we can start with by raising 4 to the third power .
By raising 4 to the third power , you should get
2 ( 64 ) - 3(4)^2 + 4(4) + 4 Now multiply 2 with 64
By multiplying 2 with 64 , you should get
128 - 3(4)^2 + 4(4) + 4 Now lets raise 4 to the 2nd power
By raising 4 to the 2nd power , you should get
128 - 3 (16 ) + 4(4) + 4 Now we can multiply 3 with 16
By multiplying 3 with 16 , you should get
128 - 48 + 4(4) + 4 We can now multiply 4 with 4
By multiplying 4 with 4 , you should get
128 - 48 + 16 + 4 Now subtract 128 with 48
By subtracting , you should get
80 + 16 + 4 Now add 80 with 16
By adding , you should get
96 + 4 Lastly , we can add 96 with 4
By adding , you should get
= 101 which is your answer
