Question

Find Zero of the Polynomial

x²−8x+15=0

Answer 1

x²-8x+15

x²-3x-5x+15

x(x-3)-5(x-3)

(x-3)(x-5)

x=3,5

Answer 2

Answer:

5 and 3

Step-by-step explanation:

we have,

x²-8x+15 = 0

x²-5x-3x+15 = 0

x(x-5)-3(x-5) = 0

(x-5)(x-3) = 0

so, now

x-5 = 0 and x-3 = 0

x = 5 and x = 3

so zeros of this polynomial are,,

5 and 3
