Question

Multiply (7x-5y)(8x+3y)


please do it fast it is my homework ​

Answer 1

Answer:

Simplifying

(7x + 3y)(8x + 5y) = 0

Multiply (7x + 3y) * (8x + 5y)

(7x * (8x + 5y) + 3y * (8x + 5y)) = 0

((8x * 7x + 5y * 7x) + 3y * (8x + 5y)) = 0

Reorder the terms:

((35xy + 56x2) + 3y * (8x + 5y)) = 0

((35xy + 56x2) + 3y * (8x + 5y)) = 0

(35xy + 56x2 + (8x * 3y + 5y * 3y)) = 0

(35xy + 56x2 + (24xy + 15y2)) = 0

Reorder the terms:

(35xy + 24xy + 56x2 + 15y2) = 0

Combine like terms: 35xy + 24xy = 59xy

(59xy + 56x2 + 15y2) = 0

Solving

59xy + 56x2 + 15y2 = 0

Solving for variable 'x'.

Factor a trinomial.

(7x + 3y)(8x + 5y) = 0
