Answer 2

Answer:

ZEROES ARE -2 AND. -7

Step-by-step explanation:

OUR QUESTION IS (x+7) (x+2)

SO ON MULTIPLYING THE QUESTION WE GET

X² + 2x + 7x+ 14. .[ x×x 2×x + 7× x + 7×2]

=>. X² + 9x + 14

BY FACTORISING METHOD WE GET

B = 9

AC = 14. THAT IS ( 7,2). WHERE [ 7+2 =9 ]. AND. [ 7 × 2 = 14]

SO IT CAN BE EXPRESSED AS

X² + 2X + 7X + 14

=> X (X+ 2 ) + 7 (X+2)

=> X+7=0. OR. X+2= 0

THERE FORE. X=-7 OR. X=-2

SO ZEROES ARE -7 AND -2
