Answer 1

Answer:

Explanation:

4.) If α and β are zeroes of quadratic polynomial than the quadratic polynomial is given by  k ( x² - ( α + β ) x + αβ )

where , ( α + β ) is sum of zeroes and αβ is product of zeroes.

Here, α = - 3 and β = 2

⇒ α + β  = -3 + 2 = -1

    αβ = -3 × 2 = -6

⇒ Quadratic Polynomial =  k ( x² - ( -1 ) x + ( -6 ) )

                                         = k ( x² + 1x - 6 )..

                                       

Therefore, Quadratic Polynomial is k ( x² + 2x - 8 )

5.) the answer is 0.

6.) 5x-4y+8=0

7x+6y-9=0

a1/a2=5/7

b1/b2=-4/6=-2/3

a1/a2 is not equal to b1/b2.

It has unique solution..

Therefore lines will intersect each other..

Hope it helps you my friend
