Answer:
9x^4+21x+6=0
Step-by-step explanation:
( 3x^2)^2+7(3x +2) -8=0
((3^2)*(x^2)^2)+(7*3x)+(7*2)-8=0
9(x^4)+21x+14-8=0
9x^4+21x+6=0
Answer:
√g *√g = g
Step-by-step explanation:
recall that any number or variable to the power of 1/2 can also be written as that variable or number under the radical.
So, we then have
√g * √g
Recall that when we multiply radicals, we multiply what is under our radicals together and then combine them under a new radical
√g * √g = √(g * g)
This gives us √(g²)
recall that the square root of a number or variable squared will merely result in the number or variable by itself (as these are reciprocate equations)
√(g²) = g
B is correct, and D is correct.
that is the answer to that question. Ive already done this question before and I got it right everytime
<h2>
Explanation:</h2>
Here we have the following expression:
So we need to extend this. Remember that the difference of squares tells us:
So here:
Thus:
