c’est à toi Réduis les expressions suivantes

c’est à toi Réduis les expressions suivantes. A = 12 – M + M² + 24M. = M² - M + 24M + 12 = M² + 23M + 12. B = 3t + 4k – 2t + 4k - k. = 3t - 2t + 4k - k = t – 3k. C = -3 + 4k – 3k² + 5 +k². = - 3k² + k² + 4k - 3 + 5 = -2k² + 4k + 2. c’est à toi

  1. c’est à toi Réduis les expressions suivantes A = 12 – M + M² + 24M = M² - M + 24M + 12 = M² + 23M + 12 B = 3t + 4k – 2t + 4k - k = 3t - 2t + 4k - k = t – 3k C = -3 + 4k – 3k² + 5 +k² = - 3k² + k² + 4k - 3 + 5 = -2k² + 4k + 2

  2. c’est à toi Réduit les expressions suivantes A = a + 5g + f + 9a – 3g - f = 9a + a + 5g – 3g + f - f = 10a + 2g B = 24x + 5y - 3y + 4x = 24x + 4x + 5y – 3y = 28x + 2y C = 24y² + 3y + 15 + 7y² - y - 2 = 24y² + 7y² + 3y – y + 15 - 2 = 31y² + 2y + 13

  3. 5 × a + 2 × 5 = 5a + 10 8 × b + 8 × 8 = 8b + 64 x × a + 2 × a = xa + 2a c’est à toi Développe les expressions suivantes 5(a + 2) = 5(x + 3 +a)= 5x+3×5+5a = 5x + 15 + 5a 8(b + 8)= d(a + 4 + h) = =da + d4 + dh (x + 2)a= 4a(2 + 5) = 4a×2 +4a×5 = 8a + 20a d²(5 + g) = 5d² + gd² 0(h + 8) = 0×h + 0×8 80 + z = 0 + 0 = 0 1(80 + z) =

  4. 4×(x + b) = 4(x + b) a×(20 + 4) = a(20 + 4) = 24a 5y – 3×5×h = 5×(y - 3×h) = 5(y-3h) c’est à toi Factorise les expressions suivantes 4x + 4b = d + 5d = d×1 + 5d = d×(1 + 5) 20a + 4a = 5ab + 5ac = 5a(b + c) 5y – 15h= 10c + 2c² = 2×5c+2×c×c = 2c(5 + c) 4y + 8j + 12k = 2w² + 7w = 2×w×w+7w = 4y + 2×4j + 3×4k = w(2w+7) = 4(y+2j+3k)
