Question

Simplify

a. x + 4
b. 9x over x - 8
c. 10x over x + 4
d. 10x to the 2nd power(x+2) over x + 6

Answer 1

`Given : ((x + 2)/(x^2 - 6x - 16))/((1)/(9x))`

`\implies (9x(x+ 2))/(x^2 - 6x - 16)`

`\implies (9x(x + 2))/(x^2 - 8x + 2x - 16)`

`\implies (9x(x + 2))/(x(x - 8) + 2(x - 8))`

`\implies (9x(x + 2))/((x - 8)(x + 2))`

`\implies (9x)/((x - 8))`
