Answer:

$\boxed{\sf \ \ 9x^2-18x-7 \ \ divided \ by \ (3x+1) \ is \ (3x-7) \ }$

Step-by-step explanation:

Hello,

let's find a and b reals so that

$9x^2-18x-7=(3x+1)(ax+b)$

$(3x+1)(ax+b)=3ax^2+(3b+a)x+b$

we identify the terms in $x^2$

9 = 3a

we identify the terms in x

-18 = 3b + a

we identify the constant terms

-7 = b

so ti goes with a = 9/3 = 3, b = -7

so we can write

$9x^2-18x-7=(3x+1)(3x-7)$

so $9x^2-18x-7 \ divided \ by \ (3x+1) \ is \ (3x-7)$

hope this helps

Find the center and radius for the circle, given the equation: x^2-14x+y^2+8=16

Strike441 [17]

You can do this by completing the square

x^2 - 14x + y^2 + 8 = 16

(x - 7)^2 - 49 + (y + 4)^2 - 16 = 16

(x - 7)^2 + (y + 4)^2 = 16 + 16 + 49 = 81

so the center is at (7 , -4) and radius = sqrt81 = 9

Solve for a 2a + ab = b

amid [387]

Answer: a= b/ b+2

Step 1: factor out variable a.

a(b+2)= b

Step 2: divide both sides by b+2.

a(b+2)/ b+2 = b/b+2
