Question

8. Rezolvați ecuațiile: a) x2 = 36; d) -2x? -72; g) -3x + 175 = -257; j) (x+4)2 = 9; b)x2 = 1600; e) x2 + 9 = 265; h) -2x2 + 27 = - 101; k) 25 - (x + 3)2 = 9; c) 5x2 = 245; f) - 14 = 155; i) (x - 3)2 = 4; 1) -144-(x - 5)2 = -22​

Answer 1

a= 18 d= 32 g =27 j= 64 b =800 e= 128 h = -4 k = 26 c = 9 f = 74 i=32
