(c) If -1 and 3 are the roots of x2 + px + 9 = 0, find the values of p and q.​

p=2, no q in equation

Step-by-step explanation:

Sum of roots=-b/a=-p

sum of -1 and 3 is -2, -p=-2, p=2

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct

but there’s no any figure there!
