Radical 6x^2 multiplied by radical 18x^2

Alina [70]

Does radical mean square root?, because radical can mean square root, cube root, fourth root, etc.

Well, I'm going to assume that radical = square root

So, if you have two square root functions, you can multiply the numbers within the square root, so you now have $\sqrt{48x^4}$ , which I'm not sure if you want it simplified or not

Paul [167]

Answer:

$(x+1)^{2} -5$

Step-by-step explanation:

$-2x=x^{2} -6 \\x^{2} +2x-6\\(\frac{b}{2}) ^{2} =(\frac{2}{2}) ^{2} =1^{2} =1\\so, (x^{2} +2x+1)-6+1\\ x^{2} +2x+1=(x+1)^{2} \\-6+1=5\\(x+1)^{2} -5$

Sorry it took so long
