Question

(06.02 LC)
Simplify (3x² - 2) + (2x² - 6x + 3).

Answer 1

Answer: x = 1, x = -1

Step-by-step explanation:

$(3x^{2} -2) + (2x^{2} -6x+3)\\3x^2 -2 +2x^2 -6x+3\\5x^2-6x^2 +1\\-x^2 +1=0\\-x^2 = -1\\x^2=1\\\sqrt{x^2}=\sqrt{1} \\x = 1, -1$

Answer 2

Group like terms, 3x^2 and 2x^2, then -6x, then -2 and 3. By grouping like terms you’ll be able to simplify the polynomial
