5a+5b+5c=-20<br> 4a+3b+3c=-6<br> -4a+3b+3c=9
tekilochka [14]
For 5a+5b+5c=-20

A= -4 - b - c

B= -4 - a - c

C= -4 - a - b

———————————

4a+3b+3c=-6

A= -3/2 - 3b/4 - 3c/4

B= -2 - 4a/3 - c

C= -2 - 4a/3 - b

———————————

-4a+3b+3c=9

A= -9/4 + 3b/4 + 3c/4

B= 3 + 4a/3 - c

C= 3 + 4a/3 - b

One of the roots of the quadratic equation x2−5mx+6m2=0 is 36. Find the greatest possible value of the second root. Help needed
Ivenika [448]
<h2>The greatest possible value of the second root, β = 54 </h2>

Step-by-step explanation:

The given quadratic equation:

x^2-5mx+6m^2=0

Let α and β be the roots of the given quadratic equation.

α = 36

To find,  the greatest possible value of the second root ( β) = ?

∴ The sum of the roots,

α + β = \dfrac{-b}{a}

⇒ 36 + β = \dfrac{-(-5m)}{1}

⇒ 5m = 36 + β               ............. (1)

The product of the roots,

α.β = \dfrac{c}{a}

⇒ 36.\beta=\dfrac{6m^2}{1}

⇒ 6.\beta=m^2                   ............. (2)        

From equations (1) and (2), we get  

⇒ (\dfrac{36+\beta}{5})^{2}=6\beta

⇒ \beta^2-78\beta+1296=0

⇒ \beta^2-54B\beta-24B\beta+1296=0

⇒ β(β - 54) - 24(β - 54) = 0

⇒ (β - 54)(β - 24) = 0

⇒ β - 54 = 0 or, β - 24 = 0

⇒ β = 54 or, β = 24

∴  The greatest possible value of the second root, β = 54
