Question

find the hcf of x square minus 1 and x square plus 3x plus 2​

Answer 1

Answer:

x+1

Step-by-step explanation:

x^2-1= (x+1)(x-1)

x^2+3x+2 = (x+1)(x+2)

hcf = x+1

Answer 2

Answer:

x square minus 1

= x^2 - 1

= (x+1)(x-1)

x square plus 3x plus 2

= x^2 + 3x + 2

= x^2 + 2x + x + 2

= x(x+2) + (x+2)

= (x+1)(x+2)

So, the HCF is,

(x+1)
