Let's start

Question - How many zeroes are possible for the following curves (i) x3 -1 (ii) x2 =7x+12

Answer -

THERE IS A CONCEPT TO FIND NO OF ZEROES

THE NUMBER ON CUTS ON X AXIS IS THE NUMBER OF ZEROES

OR

HIGHEST DEGREE = NUMBER OF ZEROES

SO IN FIRST ITS 3 THERFORE THE NUMBER OF ZEROES =3

IN SECOND IT'S 2 THEREFORE 2 ZEROES

HOPE IT HELPED

Answer 2

Answer:

Step-by-step explanation:

1)x^3-1=0

X=1

1^3-1=0

One zero is possible

2)x^2+7x+12=0

X^2+4x+3x+12=0

X(x+4)+3(x+4)=0

X+4=0 or x+3=0

X=-4 or x-3

Zeroes are -4,-3 and also -6,-1
