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)}}$$\sqrt[\square]{\frac{3(81)+45}{15-18}}$$\sqrt[\square]{\frac{243+45}{-3}}$$\sqrt[\square]{\frac{288}{-3}}$$\sqrt[\square]{-96}$

In the simplest radical form

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