Don't try anything positive.
f(-1) = 3 - 4 + 13 - 16 + 4 = 0 This one works so one factor is (x + 1)
f(-1/3) = gives a 0. So another factor is 3x + 1
The last factor is found by dividing 3x^2 + 4x + 1 into the original equation. That's (3x + 1)(x + 1) expanded.
When you do that you find that the last factor is (x^2 + 1)
You can see how this is factored at Wolframalpha dot com

What is the equation of a circle with center (2,-5) and radius 4?
azamat

Answer:

(x - 2)² + (y + k)² = 4²

Step-by-step explanation:

To answer this, we insert the given into (center x-coordinate 2, center y-coordinate -5, radius 4) into the general formula for a circle with center at (h, k) and radius r:  (x - h)² + (y - k)² = r²  →  (x - 2)² + (y + k)² = 4²

Evaluate negative 3 to the power of 2 + (2-6)(10)<br><br><br> Please help!
Tom [10]

Answer:

(2-6)(10) plus 3 to the power of 2, is <u>-31</u>.

Explanation:

Three to the power of two plus parenthesis two minus six parenthesis parenthesis ten. This is the same as the sum or addition of 3 times 3(3 times itself two times), and 2 minus 6 times 10.

This expression can be represented by (3^2) + (2-6)(10) which is (3 × 3) + (-4 × 10) which is 9 + -40 which simplifies to -31

A coupon offers $1.00 off the 16-ounce size. Which Size has the better buy then?
Marrrta [24]
Pint:
16 oz size for $3.98 - $1.00 coupon
total value: $2.98

Quart:
We have 32 oz for $5.98, but to compare the value we need 16 oz so divide both side (quantity and price by 2)
16 oz for $2.99 - $0.50 coupon
total value (16) : $2.49
total value (32): 2.49 + 2.49 = $4.98

Answer: Quart is better to buy
