radical(14)*radical(2) = 2*radical(7)
Without further information available we will consider only the square roots. The square roots of 14 are +3.741 and -3.741, similarly the square roots of 2 are+1.414 and -1.414 and so we can have four products
1) (+3.741) X (+1.414) = +5.155
2) (-3.741) x (+1.414) = -5.155
3) (+3.741) x (-1.414) = -5.155
4) (-3.741) x (-1.414) = +5.155
Expressions 1 and 4 are equal, expressions 2 and 3 are equal. Hence the product of radical 14 times radical 2 can be +5.155 or -5.155
12 radical 2 you multiply 6 and 2 :)
√2 x √2 = (√2)2 = 2
2 square root of 14
Since 60 can be factored to 4 times 15, then radical 60 equals 2 times radical 15.
The square root of 28 or in this case the radical form of 28 will be 2 times radical 7. Since 28 is 4 times 7 and the square root of 4 is two.
1 over 2 times radical 6
12 radical 2 you multiply 6 and 2 :)
√2 x √2 = (√2)2 = 2
2 times radical 5 or about 4.472135955
14√2
The square root of 12 may be simplified to 2 times the square root of 3.
-1?

First, note that radical 4 is 2. So 3xradical 4 is just 6, Now we have 6+2 radical 3. You can't do much with this except factor out a 2 if you want 2(3+Radical 3)
5 times 3 times 2 times 2. Or 2 radical 15.
put it to the power of 1/2 141/2 = 3.74
I assume you mean x(squared) + 4x - 10. Solving this isn't extremely difficult if you know the quadratic formula. first of all, remember the form ax(squared) + bx + c you are currently in that form. so, the formula is (-b +OR- radical(b(squared) - 4ac)) /2a so, using the formula, you will get (-4 + or - radical(16 - 4(1)(-10)))/2(1) this simplifies to (-4 + or - radical(56)) / 2 this can simplify to (-4 + or - radical(4) * radical(14)) / 2 the 2 in the denominator cancels out with the -4 and the 2(comes from radical(4)) in the numerator. this leaves us with -2 + or - radical(14) these are the two solutions. x= -2 + radical(14) x = -2 - radical(14) this may seem complex since it's hard to explain in this way, but I promise you will understand it. here is an easier to understand version of the quadratic formula.
