Answer:
Solution given:
Since it is a form of (a+b)²
we have
(a+b)²=a²+2ab+b²
here
a=x
b=b/2a
now
substituting value
x²+2*x*b/2a+(b/2a)²
The correct answer is C. Goodluck
Perform the operation in the choices to determine the coefficients of the terms.
(Addition) -4x - 1 + 2x + 4 = -2x + 3
(Subtraction) -4x - 1 - (2x + 4) = -6x - 5
(Multiplication) (-4x - 1)(2x + 4) = -8x² -18x -4
Thus, the answer is multiplication as it gives a numerical coefficient equal to -18.
False; 4cd cannot be added with 8c because their variables don’t match up therefore meaning they cannot be added together.
