Question

multiply 4x-3y×7x-4y​

Answer 1

Answer:

Simplifying

(7x + -4y)(4x + 3y) = 0

Multiply (7x + -4y) * (4x + 3y)

(7x * (4x + 3y) + -4y * (4x + 3y)) = 0

((4x * 7x + 3y * 7x) + -4y * (4x + 3y)) = 0

Reorder the terms:

((21xy + 28x2) + -4y * (4x + 3y)) = 0

((21xy + 28x2) + -4y * (4x + 3y)) = 0

(21xy + 28x2 + (4x * -4y + 3y * -4y)) = 0

(21xy + 28x2 + (-16xy + -12y2)) = 0

Reorder the terms:

(21xy + -16xy + 28x2 + -12y2) = 0

Combine like terms: 21xy + -16xy = 5xy

(5xy + 28x2 + -12y2) = 0

Solving

5xy + 28x2 + -12y2 = 0

Solving for variable 'x'.

Factor a trinomial.

(7x + -4y)(4x + 3y) = 0
