Question

2. Evaluate the following expression for x = 9 and express in simplest radical form:V[(3x^2 +5x)/(15-2x)]

Answer 1

V[(3x^2 +5x)/(15-2x)]

Replace x=9

`\sqrt[\square]{\frac{3(9)^2+5(9)^{}}{15-2(9)}}`
`\sqrt[\square]{(3(81)+45)/(15-18)}`
`\sqrt[\square]{(243+45)/(-3)}`
`\sqrt[\square]{(288)/(-3)}`
`\sqrt[\square]{-96}`

In the simplest radical form

`\sqrt[\square]{-1\text{ }}\text{ }\sqrt[\square]{96}`
`i4\sqrt[\square]{6}`
`4i\sqrt[\square]{6}`
