Question

Find the mean of the zeroes of the polynomals x2- 3x +2 and x2 - 6x +7
​

Answer 1

Answer:The zeros of the polynomials is-2,1,1,-7

Step-by-step explanation:

x²-3x+2=0

x²-2x-x+2=0

x(x-2)-1(x-2)=0

(x-2)(x-1)=0

x=2 or x=1

x² + 6x – 7 = 0

=

(x – 1)(x + 7) = 0

x – 1 = 0, x + 7 = 0

x = 1, x = – 7
