Question

(3x + 4) (3x − 3)solve this ​

Answer 1

Answer:

(3x+4)(3x-3)=3x²+x-4

Step-by-step explanation:

(3x+4)(3x-3)

=3x(3x-3)+4(3x-3)

=9x²-9x+12x-12

=9x²+3x-12

=3x²+x-4

Answer 2

Answer:

$\large \bold \pink{A \: } \large \bold \blue{N \: } \large \bold \red{S \:} \large \bold \purple{W \:} \large \bold \green{E \:} \large \bold \orange{R \:}$

Using identity :

(x + a)(x + b) = x² + (a + b) x + ab

Solve:-

(3x + 4) (3x − 3) = 3x² + (4 - 3) 3x + 4(-3)

= 9x² + 1 × 3x - 12

= 9x² + 3x - 12
