Solve for X and y 139x+56y=641 ,56x+139y=724 |
|
Answer» Step-by-step explanation: Let the given equations be ; 139x + 56y = 641 -------- (1) 56x + 139y = 724 --------- (2) On adding EQ. 1) & 2) we get ; 195x + 195y = 1365 195(X + y) = 1365 [ on taking 195 as common ] x + y = 1365/195 x + y = 7 ------- (3) Now, SUBTRACTING eq.2) from 1) we get, 83x - 83y = -83 83 (x - y ) = -83 x - y = -83/83 x - y = -1 ------- (4) Adding eq.3) and 4) we get ; 2x = 6 x =3 On putting value of "x" in eq.4) we get ; 3-y = -1 y = 4 |

Factorise x 4 +2x 3-13x 2-14x+24 |
|
Answer» Answer: (x-1) (x+2) (x-3) (x+4) Step-by-step explanation: Firstly, we will find the root of p(x) = x^4 + 2x³ - 13x² - 14x + 24 When x = 1 => x^4 + 2x³ - 13x² - 14x + 24 => (1)^4 + 2(1)³ - 13(1)² - 14(1) + 24 => 1 + 2 - 13 - 14 + 24 => 27 - 27 => 0 So by factor theorem, (x - 1) is a factor On dividing p(x) by (x - 1), we get x³ + 3x² - 10x -24 ☆ Refer to the attachment 1 ☆ Now find the root of p(x) = x³ + 3x² - 10x -24 When x = -2 => x³ + 3x² - 10x -24 => (-2)³ + 3(-2)²- 10(-2) -24 => -32 + 32 => 0 So by factor theorem, (x + 2) is a factor On dividing p(x) by (x + 2), we get x² + x - 12 ☆ Refer to the attachment 2 ☆ Now, USING middle term splitting : => x² + x - 12 => x² + 4x - 3x - 12 => x(x+4) - 3(x+4) => (x-3) (x+4) ∴ x^4 + 2x³ - 13x² - 14x + 24 = (x-1) (x+2) (x-3) (x+4) |
