1. Rational comes out even. 2. Irrational 8 square rooted doesn't come out even. 3. Irrational 6 square rooted doesn't come out even. 4. .3 square rooted doesn't come out even.
Multiplying both sides of a rational equation by a variable expression introduces the possibility of extraneous solutions. Therefore, we must check the solutions against the set of restrictions. If a solution is a restriction, then it is not part of the domain and is extraneous.
Answer:
x = 64
Step-by-step explanation:
2x = 128
x = 64
(3x-8)(2x^2+4x-9)= <span><span><span>6x^3</span>−<span>4x^2</span></span>−59x</span>+72<span>
Hope I helped! ( Smiles )</span>
Its 2x^2-4x, to check it add it to 3x^2-2x or
2x^(2)-4x+3x^(2)-2x
