Question

Simplify the sum.
d^2+d-30/d^2+3d-40 + d^2+14d+48/d^2-2d-48

Answer 1

factor the top and bottom of each term and tell me what you get

Answer 2

d^2+d-30

we want two numbers that multiply to -30 and add to 1, two such numbers are -5 and 6

so we have d^2-5d+6d-30

now factor out d from the first two terms and 6 from the last two terms

d(d-5)+6(d-5) now factor out (d-5)
(d-5)(d+6)

make sence?

Answer 3

sense*

c. 2d^2+15d+18 / (d+8)(d-8)
d. 2d^2+15d+18 / 2d^2+d-88
