Réduire les expressions ci-dessous
T=2y*y -(4*y*2+3y*2*-4*7)+2*y+4*(-4)
T = 2y² - (8y + 6y * - 28) + 2y - 16
T = 2y² - (8y - 168y) + 2y - 16
T = 2y² - (- 160y) + 2y - 16
T = 2y² + 160y + 2y - 16
T = 2y² + 162y - 16
U=8y*6y+2*y*5-(4*y+4*2)-y*(-3)+7
U = 48y² + 10y - (4y + 8) + 3y + 7
U = 48y² + 10y - 4y - 8 + 3y + 7
U = 48y² + 10y + 3y - 4y - 8 + 7
U = 48y² + 9y - 1.
