Solve long division methodX³+8x²-9x+30 |
|
Answer» Step-by-step explanation: The first term is, x^2 its coefficient is 1 . The middle term is, +9X its coefficient is 9 . The last term, "the CONSTANT", is +18 Step-1 : Multiply the coefficient of the first term by the constant 1 • 18 = 18 Step-2 : Find two factors of 18 whose sum equals the coefficient of the middle term, which is 9 . 3 + 6 = 9 That's it Step-3 : Rewrite the polynomial SPLITTING the middle term using the two factors found in step 2 above, 3 and 6 x2 + 3x + 6x + 18 Step-4 : Add up the first 2 terms, PULLING out like factors : x • (x+3) Add up the last 2 terms, pulling out common factors : 6 • (x+3) Step-5 : Add up the four terms of step 4 : (x+6) • (x+3) Which is the desired factorization. X³+8x²-9x+30= (x-1)(x+6)(x+3) x= 1 or x= -6 x= -3 |

17.कोई धनराशि साधारण ब्याज की दर से 4 वर्ष मेंबढ़कर 758 व 6 वर्ष में बढ़कर ३ 875 हो जातीहैं धनराशि ज्ञात कीजिए- |
|
Answer» LET the principle be X Rs rate be y% per ANUM. Therefore, Interest in 4 YEARS = x * y*4/100 =4xy/100 Amount in 4 years =X + 4xy/100 Interest in 6 years = x *y*6/100 =6xy/100 Amount in 6 years = x + 6xy/100 Now we can SAY, 6xy/100 -4xy/100 = 875- 758 :. 2xy/100 =117 :. Xy=117*50 :. xy =5850 Now, Interest in 4 years =5850*4/100 =234 Since, Amount in 4 years was 758 :. Principle = 758-234 = 524 Rs. |
