Subtract 9x^2 – 10x + 1 from -2x^2 + 4x – 10.

11x^2  −6x−9

Step-by-step explanation:

9x^2 – 10x + 1 - ( -2x^2) + 4x – 10.

The opposite of −2x^2 is 2x^2

9x^2 −10x+1+2x ^2 +4x−10

Combine 9x^2  and 2x^2  to get 11x^2 .

11x^2 −10x+1+4x−10

Combine −10x and 4x to get −6x.

11x^2 −6x+1−10

Subtract 10 from 1 to get −9.

11x^2  −6x−9

2 x^2 -3x+p

sum of roots = 3/2

let other root be x

3+ x = 3/2

x= 3/2 - 3 = -3/2

product of roots = p/2

3× -3/2 = p/2

-9 = p

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3
