Bonjour,Pour x = - 1 et y = 3
I = x² - y²
I = (- 1)² - 3²
I = 1 - 9
I = - 8
J = (x - y)²
J = (- 1 - 3)²
J = (- 4)²
J = 16
K = x² - 2x + 1
K = (- 1)² - 2 * (- 1) + 1
K = 1 + 2 + 1
K = 4
L = 2x³ - 3x
L = 2 * (- 1)³ - 3 * - 1
L = 2 * - 1 + 3
L = - 2 + 3
L = 1
V = (2x)³ - 3x²
V = (2 * - 1)² - 3 * (- 1)²
V = - 2² - 3 * 1
V = 4 - 3
V = 1
Pour x = 1/2 et y = - 5/3
I = x² - y²
I = 1/2² - (- 5/3)²
I = 1²/2² - (- 5²/3²)
I = 1/4 - (25/9)
I = 1 x 9 / 4 x 6 - 25 x 4 / 9 x 4
I = 9/36 - 100/36
I = - 91/36
J = (x - y)²
J = (1/2 - (- 5/3)²
J = (1/2 + 5/3)²
J = (1 x 3 / 2 x 3 + 5 x 2 / 3 x 2)²
J = (3/6 + 10/6)²
J = 13/6²
J = 13²/6²
J = 169/36
K = x² - 2x + 1
K = (1/2)² - 2 * 1/2 + 1
K = 1²/2² - 2/2 + 1
K = 1/4 - 2/2 + 1
K = 1/4 - 2 x 2 / 2 x 2 + 1 x 4 / 1 x 4
K = 1/4 + 4/4 + 4/4
K = 9/4
L = 2x³ - 3x
L = 2 * (1/2)³ - 3 * 1/2
L = 2 * 1³/2³ - 3/2
L = 2 * 1/8 - 3/2
L = 2/8 - 3 x 4 / 2 x 4
L = 2/8 - 12/8
L = - 10/8
L = 2 x - 5 / 2 x 4
L = - 5/4
V = (2x)³ - 3x²
V = (2 * 1/2)³ - 3 * 1/2²
V = 2/2³ - 3 * 1²/2²
V = 2³/2³ - 3 * 1/4
V = 8/8 - 3/4
V = 8/8 - 3 x 2 / 4 x 2
V = 8/8 - 6/8
V = 2/8
V = 2 x 1 / 2 x 4
V = 1/4
