Hello everyone! I’m also a math learner. For me, the Viète theorem is the most basic array in the curriculum. However, some students still feel it difficult to memorize all formulas in the Viète theorem? Don’t worry! Today, I would like to introduce to you one simple method to remember these formulas for a long time with APP RESUMIND. Let’s scroll down to the yellow text for detailed instructions!

## 1. Viète Theorem In the quadratic equation

- 1, If x1 and x2 are two roots of the quadratic equation: ax
^{2}+bx+c=0(a≠0) , we have:- S = x 1 + x 2 = -b / a
- P = x 1*x 2 = c / a

- 2, If a + b + c = 0 => the quadratic equation has a root equal to 1.
- 3, If a – b + c =0 => the quadratic equation has a root equal to -1.
- 4, The quadratic equation has two distinct roots with the same sign <=> Δ > 0 and P > 0.
- 5, The equation has two distinct roots with the opposite in sign <=>Δ > 0 and P < 0.
- 6, The equation has two distinct roots of the same positive <=> Δ > 0, S > 0 and P > 0.
- 7, The equation has two distinct roots of the same negative <=> Δ > 0, S < 0 and P > 0.

## 2. Viète Theorem in the cubic equation

- If x1, x2, and x3 are three roots of the cubic equation: ax
^{3}+bx^{2}+cx+d=0 (a≠0) , we have:- Firstly, x 1 + x 2 + x 3= -b / a
- Next, x 1 * x 2 + x 2 * x 3 + x 3 * x 1 = c / a
- Finally, x 1 * x 2 * x 3 = -d / a

## 2. How to learn quickly with RESUMIND

RESUMIND helps you learn well

RESUMIND is a subconscious development application installed on a mobile phone. This app bases on human biology and works for anyone. Humans have a mechanism: While you are dreaming in sleep, if there is a word emits, it will be remembered by the brain for a long time. Therefore, RESUMIND will give you a way to memorize the Viète theorem very simply without spending much time.

Let’s copy the Viète theorem into the application and then set the time until you almost wake up in the morning that is when your brain is the most conscious. Although you do not take much time to learn, the knowledge is still “loaded” into your brain. What is better than this? Please install the application for yourself. Have a good time!

**APP: REPROGRAM SUBCONSCIOUS MIND** helps in self-development and studying while sleeping. It evokes powerful sources of energy every day through sight and hearing. Therefore, Please use **APP: REPROGRAM SUBCONSCIOUS MIND** because it’s awesome.
