Question

Which of the following is the correct factorization of this trinomial?

Answer 1

$\implies {\blue {\boxed {\boxed {\purple {\sf { C. \: (3x - 4)(3x +4) }}}}}}$

$\large\mathfrak{{\pmb{\underline{\red{Step-by-step\:explanation}}{\red{:}}}}}$

$\: 9 {x}^{2} - 0x - 16$

➺$\: 9 {x}^{2} - 0 - 16$

➺$\: 9 {x}^{2} - 16$

➺$\: ( {3x})^{2} - ({4})^{2}$

➺$\: (3x - 4)(3x + 4)$

Note:-

♨$\:( {a})^{2} - ({b})^{2} = (a + b)(a - b)$

$\large\mathfrak{{\pmb{\underline{\orange{Mystique35 }}{\orange{☂}}}}}$

Answer 2

The answer is c. Difference of squares
