Answer:

A:- This polynomial has a degree of 2, so the equation x^2+x-12=0 has exactly 2 roots.

B:-The quadratic equation x^2+x-12=0 has two real solutions, x= 3 or x= -4

Step-by-step explanation:

1) A quadratic equation always has 2 real roots.

2) Solving the equation,

factorisation method,

x^2+x-12=0

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

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

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

thus x=3 or x=-4

Given the venn diagram, find P(brother and sister)
LUCKY_DIMON [66]

Based on the venn diagram of siblings, the probability of having a brother and sister is c. 0.33.

<h3>What is the probability of brother and sister?</h3>

The probability of having a brother and sister can be found as:

= Number of those with brother and sister / Total number of people in poll

Solving gives:

= 10 / (8 + 10 + 5 + 7)

= 10 / 30

= 0.33

In conclusion, the probability of having a brother and sister is 0.33.
