Question

Find the zeroes of the polynomial p of x=x square minus 5x+4

Answer 1

Answer:

xsquare-5x+4

Step-by-step explanation:

if x=1 1*1-5*1+4=1-5+4=5-5=0

Answer 2

Answer:

zeroes are 1 and 4

Step-by-step explanation:

p(x) = x² - 5x + 4

= x² -(4+1)x + 4

= x² - 4x - 1x + 4

= x(x - 4).-1(x - 4)

= (x - 1)(x - 4)

x - 1 = 0 , x - 4 = 0

x = 1 , x = 4
