------------------------------------------------ Which of the following is the product of [tex]$(7x + 2)$[/tex] and [tex]$(5x - 11)$[/tex]?

A. [tex]12x^2 - 10x - 77x - 22[/tex]

B. [tex]35x^2 - 67x - 22[/tex]

C. [tex]12x^2 - 67x - 22[/tex]

D. [tex]35x^2 + 67x + 22[/tex]

Answer :

To find the product of the expressions [tex]\((7x + 2)\)[/tex] and [tex]\((5x - 11)\)[/tex], we need to apply the distributive property (often referred to as the FOIL method for binomials, which stands for First, Outer, Inner, Last). Here's a step-by-step breakdown of the process:

1. Multiply the First terms:
- [tex]\(7x \cdot 5x = 35x^2\)[/tex]

2. Multiply the Outer terms:
- [tex]\(7x \cdot (-11) = -77x\)[/tex]

3. Multiply the Inner terms:
- [tex]\(2 \cdot 5x = 10x\)[/tex]

4. Multiply the Last terms:
- [tex]\(2 \cdot (-11) = -22\)[/tex]

5. Combine all the terms:
- [tex]\(35x^2 + (-77x) + 10x + (-22)\)[/tex]

6. Simplify by combining like terms:
- The [tex]\(x\)[/tex] terms: [tex]\(-77x + 10x = -67x\)[/tex]

Putting it all together, the simplified product is:

[tex]\[ 35x^2 - 67x - 22 \][/tex]

Therefore, the correct answer is option B: [tex]\(35x^2 - 67x - 22\)[/tex].
