Question

select the correct answer. what is the simplified form of the expression (x + 6)(7x - 1)? 7x^2 + 43x - 6 7x^2 + 41x - 6 7x^2 - 6 8x^2 + 5

Explanation:

Step1: Apply FOIL method

$(x + 6)(7x - 1)=x\times7x+x\times(- 1)+6\times7x+6\times(-1)$

Step2: Calculate each product

$x\times7x = 7x^{2}$, $x\times(-1)=-x$, $6\times7x = 42x$, $6\times(-1)=-6$

Step3: Combine like - terms

$7x^{2}-x + 42x-6=7x^{2}+41x-6$

Answer:

$7x^{2}+41x - 6$
