Question

If a and b are the zeroes the polynomial 2x² -4x +5 , find the value of a² + b² is​

Answer 1

Answer:

-1

Step-by-step explanation:

this equation comparing with ax2+ bx + c then we get

a= 2 b= -4 c= 5

a + b = -b/a = -(-4) /2 = 2

a× b = c/a= 5/2

a2 + b2 = (a+b)^2 -2ab

= (2) ^2 - 2× 5/2

= -1
