Answer: f(x) = x³ + x² - 26x + 24
<u>Step-by-step explanation:</u>
x = 4 x = -6 x = 1
x - 4 = 0 x + 6 = 0 x - 1 = 0
(x - 4) (x + 6) (x - 1) = 0
(x² + 2x - 24)(x - 1) = 0
x(x² + 2x - 24) -1(x² + 2x - 24) = 0
x³ + 2x² - 24x -x² - 2x + 24 = 0
x³ + x² - 26x + 24 = 0
It is important to remember that in simplifying expressions, you can only add or subtract like terms. Also, you have to follow PEMDAS. For the expression,
<span>5 + 7 + 15xy^2 + 9y^3 + 10x –13xy^2 – 3x – 8y^3
We can combine all the constants, xy^2 terms, y^3 terms and x terms which will yield,
12 + 2xy^2 + y^3 + 7x
Therefore the correct answer is option B.</span>
Answer: 80
Step-by-step explanation:
<em>The difference of, the product of three and n squared, and x.</em>
To estimate, let's round 2/9 to 2/10. That simplifies to 1/5. 1/5 * 88 = 17.6
