Question

multiply ,
$a) \: 4x + y \: \: and \: \: x + 3y$
$b) \: 2x^2 - 4x + 7y \: and \: \: 2x^2$
please send correct answer because first answer I not understood , please send with correct solution​

Answer 1

Answer:

1. 4X + Y and X + 3Y

= (4X + Y)(X + 3Y)

= 4X(X + 3Y) + Y(X + 3Y)

= 4X² + 12XY + XY + 3Y²

= 4X² + 13XY + 3Y²

• 2X² - 4X + 7Y and 2X²

= (2X² - 4X + 7Y)(2X²)

= 4X⁴ - 8X³ + 14X²Y

Answer 2

Step-by-step explanation:

1. (4x+y)(x+3y)

= 4x² + 12xy + xy + 3y²

= 4x² + 13xy + 3y²

2. (2x² - 4x + 7y)(2x²)

= 4x⁴ - 8x³ + 14x²y
