31) Without actual division, prove that x^4+2x^3-2x^2+2x-3 is exactly divisible by x^2+2x-3 |
|
Answer» p(x) = x⁴ + 2x³ - 2x² + 2x - 3 = 0 First let's factorise the given divisor, x² + 2x - 3. x² + 2x - 3 ⇒ x² + 3x - x - 3 ⇒ x(x + 3) - (x + 3) ⇒ (x - 1)(x + 3) So, if p(x) is DIVISIBLE by x² + 2x - 3, then it will be divisible by both x - 1 and x + 3 each. So we have to check WHETHER p(x) is divisible by x - 1 and x + 3. For this, without actual division, we can find it out by checking whether p(1) and p(-3) are equal to 0. p(1) = (1)⁴ + 2(1)³ - 2(1)² + 2(1) - 3 p(1) = 1 + 2 - 2 + 2 - 3 p(1) = 0 p(-3) = (-3)⁴ + 2(-3)³ - 2(-3)² + 2(-3) - 3 p(-3) = 0 So we GOT that p(1) = p(-3) = 0. Thus x - 1 and x + 3 are factors of p(x), thereby p(x) being divisible by x² + 2x - 3. Hence Proved! |

Find the value of √[√2+√3/√2-√3] , if √3=1.73 |
|
Answer» √(2+√3)/(2-√3) => √(2+√3)/√(2-√3) RATIONALIZING the denominator √(2+√3)(2+√3)/√(2-√3)(2+√3) √(2+√3)²/√(2)²-(√3)² 2+√3/√(4-3) => 2+√3/√1. (√1 = 1) => 2+√3 SINCE √3 =1.73. 2+√3 = 2+1.73 = 3.73 is the answer hope this helps |
