→ 1st quadrant ↔ ( +ve, +ve )

→ 2nd quadrant ↔ ( -ve , +ve )

→ 3rd quadrant ↔ ( -ve, -ve )

→ 4th quadrant ↔ ( +ve, -ve )

Thus, POINT ( -8, 0 ) is ( -ve, 0 (±ve) )

HENCE, ( -8, 0 ) LIES between the 2nd and 3rd quadrant. [ x' AXIS ]

solve cross multiplication question has 2 X + 3 Y equal to elevel and 2 x minus 4 Y equal to minus 24 ​

Answer»

Step-by-step explanation:

2x+3y=11•••••••••••(i)

2x-4y=-24••••••••••(ii)

from eq.n (i)

2x=11-3y•••••••••••(III)

& from eq.n (ii)

2x=-24+4y•••••••••(iv)

Now eq.n (iii)=(iv)

11-3y=-24+4y

=>-3y-4y=-24-11

=>-7y=-35

=>y=5

Now PUTTING the value of y in eq.n (iii) we GET

2x=11-3(5)

2x=11-15

2x=-4

x= -2

hence x=-2 & y= 5

Answer»

ANSWER:

x² + 3 x - ( a² + a - 2 ) = 0

==> x² + 3 x - ( a² + 2 a - a - 2 ) = 0

==> x² + 3 x - ( a ( a + 2 ) - 1 ( a + 2 ) ) = 0

==> x² + 3 x - ( a + 2 )( a - 1 ) = 0

==> x² + ( ax + 2 x - ax + x ) - ( a + 2 )( a - 1 ) = 0

==> x²  + x( a + 2 ) - x ( a - 1 ) - ( a + 2 )( a - 1 ) = 0

==> x ( x + a + 2 ) - ( a - 1 ) ( x + a + 2 )

==> ( x + a + 2 )( x - a + 1 ) = 0

IF x+1/x=4,find(i) x²+1/x²(ii) x-1/x(iii) x³-1/x³plz helpfirst one will be brainliest PLZ WRITE CORRECT ASWER

Answer»

GIVEN : x + 1/x = 4

To FIND : (I) x² + 1/x²

(ii) x - 1/x

(iii) x³ - 1/x³

solution : as it is given that, x + 1/x = 4

squaring both sides we get,

(x + 1/x)² = 4²

⇒x² + 1/x² + 2 × x × 1/x = 16

⇒x² + 1/x² + 2 = 16

⇒x² + 1/x² = 14 ......(1)

(ii) we know, (a - b)² = (a + b)² - 4ab

⇒(x - 1/x)² = (x + 1/x)² - 4 × x × 1/x

⇒(x - 1/x)² = (4)² - 4

⇒(x - 1/x)² = 16 - 4 = 12

⇒(x - 1/x) = 2√3 .........(2)

(iii) we know, a³ - b³ = (a - b)³ + 3ab(a - b)

so, x³ - 1/x³ = (x - 1/x)³ + 3 × x × 1/x (x - 1/x)

= (2√3)³ + 3(2√3)

= 24√3 + 6√3 = 30√3

so, (x³ - 1/x³) = 30√3 .............(3)
