what is the value of (3 x - 2) (4 x+1)- (3 x -2) 4 x +1 when x = 4 ?
2817
(3 x - 2) (4 x+1)- (3 x -2) 4 x +1 , when x = 4
= (10)(17) - (10)(16) - 1
= 170 - 160 - 1
= 9
if you meant:
(3 x - 2) (4 x+1)- (3 x -2)( 4 x +1)
then you get 0 , since (10)(17) - 10(17) = 0
To find the value of the expression (3x - 2)(4x + 1) - (3x - 2)(4x + 1) when x = 4, we can follow these steps:
Step 1: Substitute the value of x into the expression.
Let's replace every x with 4:
(3(4) - 2)(4(4) + 1) - (3(4) - 2)(4(4) + 1)
Step 2: Perform the operations within parentheses.
Calculate:
(12 - 2)(16 + 1) - (12 - 2)(16 + 1)
Step 3: Simplify the calculations.
Multiply within each set of parentheses first:
(10)(17) - (10)(17)
Step 4: Apply the subtraction operation.
Subtract the result within the second set of parentheses from the result within the first set of parentheses:
170 - 170
Step 5: Perform the final calculation.
Subtract the two values:
0
Therefore, the value of the expression (3x - 2)(4x + 1) - (3x - 2)(4x + 1) when x = 4 is 0.
