Solving quadratic equations x²-13x=30 |
|
Answer» X² -13x + 30 = 0 => To solve by middle splitting term we multiply the constant and COEFFICIENT of x² So, here coefficient of x² is 1 and constant term is 30 Now we have to find LCM of 30 LCM = 2× 3 × 5 Now we have either by subtracting or by adding we have to get -13 as middle one. so, we can do it like :+ x² -10x -3X +30 = 0 X (x -10 ) -3 ( x -10) =0 (x -3 ) ( x - 10 ) =0 |
