Question

resolver las siguientes operaciones matematicas

a (6x+3)(7x-2)=

b (7x+y)(2x+5y)=

Answer 1

A. (6x + 3)(7x - 2)

(6x + 3)(7x - 2)

6x × 7x - 6x × 2 + 3 × 7x - 3 × 2

42x² - 12x + 21x - 6

42x² + 9x - 6

B. (7x + y)(2x + 5y)

(7x + y)(2x + 5y)

7x × 2x + 7x × 5y + 2xy + y × 5y

14x² + 35xy + 2xy + 5y²

14x² + 37xy + 5y²
