You didn't specify the topic so I will solve it in 3 topics
solving for a, you take roots of both sides and solve a=18,-18
using the quadratic formula, solve the equation for aa by finding aa, bb, and ccof the quadratic then applying the quadratic formula.

a=±√321a=±321

a≈17.91647286,−17.91647286


for factoring, Factor and set each factor equal to zero.

a=√321,−√321a=321,-⁢321

a≈17.91647286,−17.91647286

342 = a²

switch sides:

for x² = f(a) the solutions are x = √ f(a)   and - √ f(a)

therefore:

√ 342 = 18

-√ 342 = - 18

a = 18  and a = - 18

hope this helps!

Answer:

Option B is the correct answer

Step-by-step explanation:

Center of the circle lie on point (-1, - 3) = (h, k)

\implies \: h =  - 1 \:  \: k =  - 3 \\radius \: r \:  = 2  \\ equation \: of \: circle \: in \: standard \: form \:  \\ is \: given \: as :  \\  {(x - h)}^{2}  +  {(y - k)}^{2}  =  {r}^{2}  \\  {(x  +  1)}^{2}  +  {(y  +  3)}^{2}  =  {2}^{2}  \\  \purple{ \boxed{ \bold{ {(x  +  1)}^{2}  +  {(y  + 3)}^{2}  = 4}}}

What is the quotient of (x3 + 6x2 + 11x + 6) ÷ (x2 + 4x + 3)? x + 2 x – 2 x + 10 x + 6
evablogger [386]

Answer:

x + 2

Step-by-step explanation:

If we know one of the factors, we should be able to use long division.

We can divide the trinomial by the binomial and find the other factor.

                 <u>x  +  2</u><u>                   </u>

x² + 4x + 3)x³ + 6x² + 11x + 6

                  <u>x³ + 4x² + 3x</u>

                         2x² + 8x + 6

                         <u>2x² + 8x + 6</u>

                                           0

Thus,

\dfrac{x^{3} + 6x^2 + 11x + 6} {x^{2} + 4x + 3} = \mathbf{x + 2}
