Answer 1
(2x + 4) by (6x + 5)
= 2x(6x + 5) + 4(6x + 5)
= 12x² + 10x + 24x + 20
= 12x² + 34x + 20
Answer 2
(5x² + 3y²) by (2x² + 4y)
= 5x²(2x² + 4y) + 3y²(2x² + 4y)
= 10x⁴ + 20x²y + 6x²y² + 12y³
Answer 3
(⅖x - ¼y) by (⅓x - ½y)
= ⅖x(⅓x - ½y) - ¼y(⅓x - ½y)
= ¼x² - ⅕xy - (1/12)xy + ⅛y²
= ¼x² -(17/60)xy + ⅛y²
Answer 4
(x⁵ + y⁵) by (x³ + y³)
= x⁵(x³ + y³) + y⁵(x³ + y³)
= x⁸ + x⁵y³ + y⁵x³ + y⁸
Answer 5
(0.5x - 2.5y) by (0.2x + 0.8y)
= 0.5x(0.2x + 0.8y) - 2.5y(0.2x + 0.8y)
= 0.1x² + 0.4xy - 0.5xy - 2y²
= 0.1x² + 0.9xy - 2y²
Hope my answer helped you, cheers :)
