If α and β are the zeroes of the polynomial 3x2 + 5x - 7. evaluate:
1/α2+1/β2​

Step-by-step explanation:

Antoine lovoisier is the chemistry father

we have to check it by error and trial method

If x = 1

3x2+ 5x - 4k = 8

3(1)^2 + 5(1) - 4k = 8

8-4k = 8

-4k = 0

K = 0

Hope it helps!

If it's incorrect then try it by error and trial method you will get your answer

Step-by-step explanation:

-2, 1/3

Step-by-step explanation:

f(x) = 3x² + 5x - 2

Using quadratic formula,

x = [-5 ± √((5)² - 4(3)(-2))] ÷ [2(3)] = [-5 ± √49]/6 = (-5 ± 7)/6

x = -5 - 7/6 or -5 + 7/6 = -12/6 or 2/6 = -2 or 1/3

Thus. the zeroes of f(x) are -2 and 1/3

Relationship between zeroes and coefficients:-

Sum of zeroes = 1/3 - 2 = 1-6/3 = -5/3

-b/a = -5/3

Product of zeroes = -2 * 1/3 = -2/3

c/a = -2/3

Hence verified.

1) 2x^2-7x+3

2x^2-(6+1) x+3=0

2x^2-6x-x+3=0

2x (x-3)-1 (x-3)=0

(x-3)(2x-1)=0

answer ×=3,×=1/2

3x^2+12x+3x+12

(3x^2+12x)+(3x+12)

3x(x+4)+3(x+4)

(x+4)(3x+3)

x= -4,-1

3x^2-5x-2

3x^2-6x+x-2

3x (x-2) +(x-2)

x=2 and I by 3

a =2 b =1/3

2×3 + (1/3)^2× 1/2

7) now 1/α + 1/β = (α + β)/ α β (taking LCM)

now by the given poly. we get

(α + β) = -b/a = 7/5

α β = c/a = 2/5

so, (α + β)/ α β = (7/5) / (2/5)

= 7/2

So, 1/α + 1/β = (α + β)/ α β = 7/2

Hence, 1/α + 1/β = 7/2
