Question

Find the zeroes of the quadratic polynomial (x + 5) (x – 6)​

Answer 1

Answer:

Standard Algebraic Identities List

Identity I: (a + b)2 = a2 + 2ab + b2

Identity III: a2 – b2= (a + b)(a – b)

Identity IV: (x + a)(x + b) = x2 + (a + b) x + ab.

Identity V: (a + b + c)2 = a2 + b2 + c2 + 2ab + 2bc + 2ca.

Identity VI: (a + b)3 = a3 + b3 + 3ab (a + b)

Answer 2

Answer:

-5 and 6

Step-by-step explanation:

(x + 5) (x – 6)=0

(x + 5)=0 and (x – 6)=0

x = -5 and x = 6
