Find any three solution x-5y=12

Answer»

We have

X+ 5y = 12


if we put X= 0 then,

0+5y = 12
y= 12/5


if we put y = 0 then,

X+5(0)= 12
X=12


if we put X= 1 then

1+ 5y = 12
5y = 12-1
5y = 11
y =11/5


u can put other no. as value of X or y .

(x+1/x)=3 the value of (x²+1/x²)

Answer»

( X + 1 / x ) = 3

Squaring both sides,

( x + 1 / x ) ^ 2 = 3 ^ 2

x ^ 2 + 1 / x ^ 2 + 2 * x * 1 /x = 9

x ^ 2 + 1 / x ^ 2 + 2 = 9

x ^ 2 + 1 / x ^ 2 = 9 -2

Find the sum and product of zeros of polynomial 2x^3-4x^2+3x-8

Answer»

Hey!!!!

=> 2x³ - 4x² + 3x - 8

So

= > \alpha + \beta + \gamma = \frac{ - b}{a}

= > \alpha + \alpha + \gamma = \frac{4}{2}

= > \alpha + \beta + \gamma = 2

So,

= > \alpha \beta \gamma = \frac{ - d}{a}

= > \alpha \beta \gamma = \frac{8}{2}

= > \alpha \beta \gamma = 4
