Question

Find the zeroes of the polynomial

X square + 7x + 10

​

Answer 1

by splits division method

x²+7x+10

x(x+5)+2(x+5)

two zeroes are,

(x+2) and (x+5),

x=-2 and x=-5

Answer 2

Answer:

x²+7x+10 = 0

By using splitting middle term method, we have

x²+(5x+2x)+10 = 0

x²+5x+2x+10 = 0

x(x+5)+2(x+5) = 0

(x+5)(x+2) = 0

Hence, x = -5 and -2.
