As f(x)=2x2+5x+k So alpha+beeta=-5/2 as -co eff of x /coeff of xsquare So alpha*beeta=k/2 constant/ co eff of x square So now your equation is - (alpha +beta)square + alpha*beeta =21/4 So by replacing values (-5/2)square+k/2=21/4 25/4+k/2=21/4 Transpose 25/4 to rhs k/2=21/4-25/4 k/2=-4/4 k=-4/4*2 k=-2 I hope your doubt is cleared best of luck for future

In arithmetic, Euclidean division – or division with remainder – is the process of dividing one integer by another, in a way that produces a quotient and a remainder smaller than the divisor.

Arjun Kumar Gupta 4 years, 5 months ago

According to Euclid's Division Lemma if we have two positive integers a and b, then there exist unique integers q and r which satisfies the condition a = bq + r where 0 ≤ r < b. That means, on dividing both the integers a and b the remainder is zero. ...

Ans:To do it systematically, find HCF of(616 and 32)= So, 616>32 616=32×19+8 32=8×4+0 So, HCF of 616 and 32 is 8(common HCF). Thus, the maximum number of columns is 8 in which they can march.

(X)2 + 6(2) =14 First of all, we have to divided by 2 both sides (X)2 /2 + 6(2) /2 =14/2 Then we have, X +6 =7 X = 7-6 X = 1 Okay, then check (1)2 + 6(2) = 14 2 + 12 = 14 14 =14

Let number of boys who took part in the quiz = x Let number of girls who took part in the quiz = y According to given conditions, we have x + y = 10… (1) And, y = x + 4 ⇒ x – y = −4 … (2) For equation x + y = 10, we have following points which lie on the line For equation x – y = –4, we have following points which lie on the line We plot the points for both of the equations to find the solution. We can clearly see that the intersection point of two lines is (3, 7). Therefore, number of boys who took park in the quiz = 3 and, number of girls who took part in the quiz = 7. (ii) Let cost of one pencil = Rs x and Let cost of one pen = Rs y According to given conditions, we have 5x + 7y = 50… (1) 7x + 5y = 46… (2) For equation 5x + 7y = 50, we have following points which lie on the line For equation 7x + 5y = 46, we have following points which lie on the line We can clearly see that the intersection point of two lines is (3, 5). Therefore, cost of pencil = Rs 3 and, cost of pen = Rs 5
