Ex 8.4, 3 Simplify. (ii) (š‘Ž^2+5) (š‘^3+3)+5Here, there are 2 expressions: 1st expression = (š‘Ž^2+5) (š‘^3+3) 2nd expression = 5 Solving 1st expression (š’‚^šŸ+šŸ“) (š’ƒ^šŸ‘+šŸ‘) = š‘Ž^2 (š‘^3+3)+5(š‘^3+3) = (š‘Ž^2Ɨš‘^3 )+(š‘Ž^2Ɨ3)+(5Ɨš‘^3 )+(5Ɨ3) = š’‚^šŸ š’ƒ^šŸ‘+šŸ‘š’‚^šŸ+šŸ“š’ƒ^šŸ‘+šŸšŸ“ Now, our expression is (š’‚^šŸ+šŸ“) (š’ƒ^šŸ‘+šŸ‘)+šŸ“ = š‘Ž^2 š‘^3+3š‘Ž^2+5š‘^3+15+5 = š’‚^šŸ š’ƒ^šŸ‘+šŸ‘š’‚^šŸ+šŸ“š’ƒ^šŸ‘+šŸšŸŽ
