Homeschool. The algebra problem?
Click OK. So I'm in school online. Frankly my mentor is helping a lot, so guess why not call them mentors and teachers. My mother is not very good at algebra. So, you do not have a teacher such as public schools is more difficult to learn certain subjects. Algebra, obviously, the problem is my problem. I work in second grade and I'm stuck. I will write to both types of problems I work and I would be very grateful if someone could show me step by step how to solve each problem, so I can understand what I am required to complete lessons and testing. Question 1. Enter any solution of this equation. 5a-14 y ^ 2 =- Q 2. I have no idea how to write about issues if I can descirbe mutlple election asking what it is. I must choose the correct way to represent the solution using the quadratic formula. 2x ^ 2 + x-6 = 0 Thanks in advance for the help. It is greatly appreciated.
Both are problems that can be solved with the quadratic formula, if you buy them in the form: Ax ² + Bx + C = 0 Question 1: Add the two sides ² and ² + 5y – 14 = 0 You can solve this with factoring: (y – 2) (y + 7) = 0 and y = 2 or = -7 The smallest solution is -7. However, the problem calls specifically to use the quadratic formula. A = 1 b = 5 c = -14 …… -5 ± √ (² 5 – 4 (1) (-14)) y = —————————– .. . ………… 2 (1) …… -5 ± √ (25 +56) y = ———————- …………… 2 …… -5 ± √ 81 y = ————— …………… 2 …… -5 ± 9 years = ———- ………. 2 y = (-5 to 9) / 2 = -14 / 2 = -7 y = (-5 + 9) / 2 = 4 / 2 = 2 small answer is: y = -7 PS This corresponds to the response found with factoring. QUESTION 2: 2x ² + x – 6 = 0 a = 2 b = c = 1 -6 Now plug that into the quadratic formula: …… -B ± √ (b ² – 4ac) x = ———————- …………… The 2nd …… -1 ± √ (1 ² – 4 (2) (-6)) x = ———————- ……… . ….. 2 (2) …… -1 ± √ (1 + 48) x = ———————- …………… 4 …… -1 ± √ 49 x = ————– …………. 4 …… -1 ± 7 x = ———- ………. 4 x = -1 / 4 ± 7 / 4 x = -8 / 4 or 6 4 / A. x = -2 or x = 1 ½
