Question

5. Realiza los siguientes productos:
a. 6(a? - ab + b?)=
b. -2 (m? + +p2) =
c. 5x (x² - 3x + 7) =
6. Calcula los siguientes productos:
a. (2x + 3) ( 7x + 4) =
b. (2a +5) (a - 3) =
C. (x + y) ( 2x - xy + y) =​

Answer 1

$5. \\ 6( {a}^{2} - ab + {b}^{2} ) \\ 6 \times {a}^{2} - 6 \times ab + 6 \times {b}^{2} \\ 6 {a}^{2} - 6ab + 6 {b}^{2} \\ \\ - 2( {m}^{2} + {p}^{2} ) \\ ( - 2) \times {m}^{2} + ( - 2) + \times {p}^{2} \\ - 2 {m}^{2} + (- 2 {p}^{2} ) \\ - 2 {m}^{2} - 2 {p}^{2} \\ \\ 5x( {x}^{2} - 3x + 7) \\ 5x \times {x}^{2} - 5x \times 3x + 5x \times 7 \\ 5 {x}^{3} - 15 {x}^{2} + 35x$

$6. \\ (2x + 3) ( 7x + 4) \\ 14 {x}^{2} + 8x + 21x + 12 \\ 14 {x}^{2} + 29x + 12 \\ \\ (2a +5) (a - 3) \\ 2 {a}^{2} - 6a + 5a - 15 \\ 2 {a}^{2} - a - 15 \\ \\(x + y) ( 2x - xy + y) \\ 2 {x}^{2} - {x}^{2} y + xy + 2xy - x {y}^{2} + {y}^{2} \\ 2 {x}^{2} - {x}^{2} y + 3xy - x {y}^{2} + {y}^{2}$

Espero sea lo que necesitas.
