Answer» Answer: 1 Step-by-step explanation: ⇒ 3 + √2 ⇒ ( 3 + √2 )( 3 - √2 ) / ( 3 - √2 ) USING ( a + b )( a - b ) = a^2 - b^2 ⇒ [ 3^2 - ( √2 )^2 ] / ( 3 - √2 ) ⇒ [ 9 - 2 ] / ( 3 - √2 ) ⇒ 7 / ( 3 - √2 ) in the question, REPLACING ( 3 + √2 )^x by [ 7 / ( 3 - √2 ) ]^x ⇒ ( 3 - √2 )^x + [ 7 / ( 3 - √2 ) ]^x = 6 Let ( 3 - √2 )^x = a ⇒ a + 7/a = 6 ⇒ ( a^2 + 7 ) / a = 6 ⇒ a^2 + 7 = 6a ⇒ a^2 - 6a + 7 = 0 Using QUADRATIC eq. ⇒ a = [ 6 ± √( 36 - 28 ) / 2 ⇒ a = [ 6 ± √8 ] / 2 ⇒ a = [ 6 ± 2√2 ] / 2 ⇒ a = 2( 3 ± 2√2 ) / 2 ⇒ a = 3 ± √2 taking -ve value HENCE, ⇒ a = ( 3 - √2 )^x = 3 - √2 ⇒ ( 3 - √2 )^x = ( 3 - √2 )^1 Comparing ⇒ x = 1 |

If p and q are zeroes of polynomial x^2 + 2x - 1, find p - q |
|
Answer» <P>Given that p and Q are zeroes of x² - 2x - 1 To find (p - q) It's known that for a quadratic equation of the form of ax² + bx + c, sum of zeroes = -b/a product of zeroes = c/a Here, in x² + 2x - 1, a = 1, b = 2 and c = -1 zeroes = p and q Hence, p + q = -(2)/1 = -2 PQ = -1/1 = -1 Now p + q = -2 → (p + q)² = (-2)² → p² + q² + 2pq = 4 SUBTRACTING 4pq from both sides → p² + q² + 2pq - 4pq = 4 - 4pq → p² + q² - 2pq = 4 - 4(-1) → (p - q)² = 4 + 4 → (p - q)² = 8 → p - q = ± √8 Or, p - q = ±2√2 |

If p and q are zeroes of polynomial x^2 + 2x - 1, find p - q ( x^2 means x square) |
|
Answer» Answer: 2√2 Step-by-step explanation: We know, polynomials written in form of x^2 - SX + P refer S as sum of their roots and P as product of their roots. Which, here, in pol. x^2 + 2X - 1 sum of roots = p + q = - 2 product of roots = PQ = - 1 Square on both sides of p + q ⇒ ( p + q )^2 = ( - 2 )^2 ⇒ p^2 + q^2 + 2pq = 4 ⇒ p^2 + q^2 + 2( - 1 ) = 4 ⇒ p^2 + q^2 - 2 = 4 ⇒ p^2 + q^2 = 4 + 2 = 6 Subtract 2pq from both sides ⇒ p^2 + q^2 - 2pq = 6 - 2pq ⇒ ( p - q )^2 = 6 - 2( - 1 ) ⇒ ( p - q )^2 = 6 + 2 = 8 ⇒ p - q = √8 ⇒ p - q = 2√2 |

In fig.5.43.Prove that. |
|
Answer» in the figure given AP is equal to QC and AP is PARALLEL to QC if in a quadrilateral opposite sides are equal and parallel, it is a parallelogram. So, APCQ is a parallelogram. AC is a DIAGONAL in parallelogram APCQ. we know that diagonal in a parallelogram divides the parallelogram into two congruent triangles. so,∆APC is congruent to ∆AQC. in a parallelogram opposite sides are equal so PC is equal to AQ. in a parallelogram opposite sides are parallel so PC is parallel to AQ. in the beginning of the solution itself we have prove that APCQ is a parallelogram hence provedMARK AS BRAINLIEST |

In the given figure , AB = BC and AC= CD, prove that angle BAD : angle ADB = 3:1 |
|
Answer» ANSWER:In the diagram, we have TWO ISOSCELES TRIANGLES. For ΔABC, AB= BC and for ΔACD, AC= CD In isosceles triangle, the two ANGLES opposite to the equal sides are also equal. So, for ΔABC, ∠BAC = ∠ACB and for ΔACD, ∠CAD = ∠ADC As ∠ACB is outside angle of ΔACD , so ∠ACB = ∠CAD + ∠ADC ⇒ ∠ACB = 2× ∠ADC (As, ∠CAD = ∠ADC ) ⇒ ∠BAC = 2× ∠ADC (As, ∠BAC = ∠ACB ) Now, according to the diagram, ∠BAD - ∠CAD = ∠BAC ⇒ ∠BAD - ∠ADC = 2× ∠ADC [As, ∠CAD = ∠ADC and ∠BAC = 2× ∠ADC] ⇒ ∠BAD = 3× ∠ADC ⇒ ∠BAD = 3× ∠ADB [As, ∠ADC and ∠ADB are same angles] ⇒ (Prov
