The first answer is correct because the terms are alike in both expressions
-2x^4 + 10x^3 - 21x^2 + 19x - 4
that should be the right answer
Answer:
around 3
Step-by-step explanation:
A solution to an equation is a number that can be plugged in for the variable to make a true number statement. Example 1: Substituting 2 for x in. 3x+5=11. gives.
√4 + <span>3√9 = 2+3*3 = 11.
This is a rational number, since the answer can be express as a fraction (e.g., 11/1).
This does not hold for square roots in general. For example </span>√3 is irrational.
