Question

write the polynomial 3x⁴-5x²-7 in index form
​

Answer 1

Step-by-step explanation:

Well this question is about solving equations so what we need to do first is get x by itself on the left hand side of the equation. We need to take the +1 over to the right hand side where it will become -1 (inverse rule) so the equation is now 1/x = 5/2 - 1 5/2 is the same as 5 divided by 2 which is 2.5 so 2.5 - 1 = 1.5 or 3/2 as a fraction so 1/x = 3/2 now we need to multiply the denominators by the opposite numerators (kriss kross) so we get 2 x 1 = 3 x X 2 = 3X no we divide both sides by 3 so x = 2/3
