6 (a + b)2 x2 + 5 (a + b)cx – 6c2 = 0solve by completing the square |
|
Answer» 6(a + b)²x² + 5(a + b)cx - 6c² = 0 ⇒(a + b)²x² + (5/6)(a + b)cx - c² = 0 ⇒{(a + b)x}² + 2.(5c/12).(a + b) x - c² = 0 adding (5c/12)² both SIDES, ⇒{(a + b)x}² + 2(5c/12).(a + b)x + (5c/12)² - c² = (5c/12)² ⇒{(a + b)x + 5c/12}² - c² = (5c/12)² ⇒{(a + b)x + 5c/12}² = c² + (5c/12)² ⇒{(a + b)x + 5c/12}² = (144 + 25)c²/144 ⇒{(a + b)x + 5c/12}² = (13C/12)² TAKING square ROOT both sides, ⇒(a + b)x + 5c/12 = ± 13c/12 ⇒(a + b)x = (-5c ± 13c)/12 ⇒x = (-5c ± 13c)/12(a + b) HENCE, x = -3c/2(a + b) , 2/3(a + b) |
