Question

If A,B and Y are zeros of polynomial p(x) = x³ - 4x² + 5x -2 then value of A+B+Y is
​

Answer 1

Step-by-step explanation:

$\</strong><strong>textbf</strong><strong> [ / t e x]$

p(x)=x³-4x²+5x-2

x(x²-4x+5)-2=0

x=2

x²-4x+5=0

x²-5x+x-5=0

x=5

x=-1

A+B+Y

2+5-1

Answer 2

HERE IS UR ANSWER DEAR,

x³ - 4x² + 5x -2= 0

x ( x²-4x +5)-2 = 0

x²-4x + 5 = 0 ; x-2=0

x²-(-5+1)x+5=0 ; x = 2

x²+5x+1x +5= 0

x(x+5)+1(x+5)= 0

(x+5) ( x+1) = 0

x+5= 0 ; x+1= 0

x= -5. ; x = -1

therefore

• A= 2
• B= -5
• C= -1

A+B+Y = 2 -5-1 = -4
