Question

(x-1) (x^2+9x-10)
please I want urgently​

Answer 1

Step-by-step explanation:

suppose x²+9x-10 = f(x)

if (x-1) is the factor of the polynomial x²+9x-10,

f(1) = 0

f(x) = x²+9x-10

f(1) = 1²+9*1-10

= 1+9-10

= 10-10

= 0

this is proved that (x-1) is the factor of the polynomial x²+9x-10
