Answer 39

are you sure you're not missing anything

Answer 40

the expression can be simplified beyond that.

let A and B be constants such that

(2x+3)/(x^2-2x-15) = A/(x-5) + B/(x+3)

multiply both sides by (x-5)(x+3)

(2x+3) = A(x+3) + B(x-5)

let x = -3 to eliminate the term with A and solve for B; likewise let x = 5 to solve for A. A and B should both be fractions which you can enter in the corresponding numerator and denominator blanks.

Answer 41

What do you mean "multiply both sides by (x-5)(x+3)"

Answer 42

both the demoninators ?

Answer 43

ok nvm i got it, thank you
