  • What is the product of (2x-7) and (3x + 3)?

==================================

[tex]\large\sf\underline{Answer:}[/tex]

[tex]\qquad \qquad \huge \rm Letter\:B.[/tex]

==================================

[tex]\large\sf\underline{Solution:}[/tex]

Here we have the given choices:

  • A. 6x2 + 15x-21
  • B. 6x2 - 15x - 21
  • C. 6x2 + 15x + 21
  • D. 6x2 - 15x + 21

Solve this equation using the distributive property,where you multiply each term to get the number.

[tex] \rm2x - 7 = \boxed{ 6} \: \bigg| \small\boxed{\: 6 {x}^{2} } \\ \rm (7)(3) = \boxed{21} \bigg | \boxed{\: 21 x} \\ \\ \qquad \rm6x^{2}+(6x- 21x)-21 \\ \qquad \boxed{ \rm6 {x}^{2} + 15x - 21}[/tex]

Therefore, the correct option is letter B.
