Answer»

$Sum \: of \: <klux>ZEROES</klux> \: =(α+β)= \frac{<klux>2</klux>}{ 3 } + \frac{ - 1}{2} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{4 - 3}{6} = \frac{1}{6} = \frac{ - b}{a} \: \: \: \: \: \: \: \: \: \\ Product\: of \: zeroes = \alpha \beta = \frac{2}{3} \times \frac{ - 1}{2} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{ - 1}{3} = \frac{c}{a} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:$

For quadratic polynomial

x²-(sum of zeroes)X +(Product of zeroes)=0

x²-(1/6)x+(-1/3)=0

${x}^{2} - \frac{ x}{6} + \frac{ - 1 }{3} = 0 \\ 6 {x}^{2} - x - 2 = 0$

Comparing the given polynomial( 6x²+ax - b = 0) with 6x²-x - 2 = 0, we get

Hey guys solve this question..........

Answer»

Step-by-step explanation:

PR > PQ & PS bisects ∠QPR

To PROVE:

∠PSR > ∠PSQ

Proof:

∠PQR > ∠PRQ — (i) (PR > PQ as angle opposite to LARGER side is larger.)

∠QPS = ∠RPS — (ii) (PS bisects ∠QPR)

∠PSR = ∠PQR +∠QPS — (iii)

(exterior angle of a triangle EQUALS to the sum of opposite interior ANGLES)

∠PSQ = ∠PRQ + ∠RPS — (iv)

(exterior angle of a triangle equals to the sum of opposite interior angles)

Adding (i) and (ii)

∠PQR + ∠QPS > ∠PRQ + ∠RPS

⇒ ∠PSR > ∠PSQ [from (i), (ii), (iii) and (iv)]

=========================================

Hope this will help you.......

33.	What is the natural these of decimal expension of rational and irational no
Answer» Answer: We know that any RATIONAL NUMBER will have either terminating DECIMAL expansion or a NON teminating recurring decimal expansion. Hence, an irrational number is a number which CONTAINS non-terminating and non-recurring decimal expansion. Hence, they are irrational numbers. In the case of irrational numbers, the decimal expansion does not terminate, nor end with a repeating sequence. For example, the decimal representation of π starts with 3.14159, but no finite number of digits can represent π exactly, nor does it repeat.

if 20% is 2200 rs then

marked PRICE is = 2200/20 × 100

marked price is = 11000 rs

so DISCOUNTED price is = marked price - discount
