How to simplify quadratic equations? Answer: You can use three ways: ▪ Completing the Square ▪By Factoring ▪Using the formula⬆ Factoring: ▪Combine all of the like terms and move them to one side of the equation. 2x^2-8x-4=3x-x^2 ➡ 2x^2 + x^2 - 8x -3x -4 = 0 ➡ 3x^2 - 11x -4=0 ▪Factor the expression. 3x^2 - 11x -4=0 ➡ (3x + 1)(x-4)=0 3x + 1 = 0 ; x - 4 = 0 ○Set each set of parenthesis equal to zero as separate equations. ▪Solve each "zeroed" equation independently 3x + 1 = 0 ; x - 4 = 0 3x + 1 = 0 ; x - 4 =0 3x = -1 ; x = 4 X = -1/3 ▪Substitute the 2 values ○Check x = -1/3 in (3x + 1)(x – 4) = 0: (3-1/3 + 1)(-1/3 – 4) = 0 (-1 + 1)(-4 1/3) 0 0=0 ○ Check x = 4 in (3x + 1)(x - 4) = 0: (34 + 1)(4 – 4) = 0 (13)(0) = 0 0=0 ◆ So, both solutions do "check" separately, and both are verified as working and correct for two different solutions. Using the Quadratic Formula: (The formula was attached to my answer to your question all you need to do is substiture the value...
Can earth science and life science ever be separated .why or why not? Answer: Yes Explanation: Earth science deals with study on the physical constitution of the planet earth and also its atmosphere. While life science deals with the study of the living organism. Although, in studying living things, it also touches the concepts of geosphere, atmosphere, hydrosphere, biosphere which is part of the concept in studying earth science. Living organism needs land (geosphere), water (hydrosphere), air (atmosphere) in order to live.
