Answer 2

Hey friend, Harish here.

Here is your answer:

To find,

(5x+7) × (3x +4)

Solution,

(5x + 7) × ( 3x + 4) = (5x × 3x) + (5x × 4) + (7 × 3x) + (7 × 4)

                              = 15x² + 20x + 21x + 28

                              = 15x² + 41x + 28.

Therefore (5x+7)(3x+4) is equal to 15x² + 41x +28.
