Question

1) Find the zeros of the polynomial .
(a) X2 + 7x + 10
(b) x2 - 25​

Answer 1

Step-by-step explanation:

This can be found by using factorisation method..

Answer 2

Answer:

X² + 7x +10 = 0

Ln= 10

X² + 2x + 5x + 10

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

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

X = - 5 or - 2

B) X² - 25 =0

X² =25

X = 5
