f(x) = 3x2 + 5x + 2fprime(x) = 6x + 5
x=6
If X = 4 then 5X is equal to 5 x 4 which is 20. So 20 + 2 = 22.
Differentiate the function with respect to x: d/dx (x3 - 2x2 - 5x + 6) = 3x2 - 4x - 5 Set this derivative = 0 and solve. 3x2 - 4x - 5 = 0 implies that x = -0.7863 or 2.1196 (to 4 dp)
5x+3y
5x plus 3 does equal 3 plus 5x; commutative law.
(3x2 + 2x + 1)
Yes, it crosses at (0.23,0) and (1.43,0).
3x2 + 5x + 2 is a quadratic expression that can be factored as follows: 3x2 + 5x + 2 = 3x2 + 3x + 2x + 2 = 3x(x + 1) + 2(x + 1) = (3x + 2)(x + 1)
It is: 3x2-5x-2 = 0 and the value of x is -1/3 or 2 when solved
Yes
x is 12
f(x) = 3x2 + 5x + 2fprime(x) = 6x + 5
If: 3x-7 = 5x+13 Then: x = -10
That depends on what the value of x is.
8x + 5x + 2x + 4x = 114 19x = 114 x = 6 then 5x + 3 = 5*6 + 3 = 33
