Solve x^2+2x+7=0 using the quadratic formula.

Aneli [31]

Answer:

$x=-1\pm \sqrt{6}i$

Step-by-step explanation:

$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$

$x=\frac{-(2)\pm\sqrt{2^2-4(1)(7)}}{2(1)}$

$x=\frac{-2\pm\sqrt{4-28}}{2}$

$x=\frac{-2\pm\sqrt{-24}}{2}$

$x=\frac{-2\pm\sqrt{-1*24}}{2}$

$x=\frac{-2\pm\sqrt{-1}\sqrt{24}}{2}$

$x=\frac{-2\pm i\sqrt{4*6}}{2}$

$x=\frac{-2\pm i\sqrt{4}\sqrt{6}}{2}$

$x=\frac{-2\pm2i\sqrt{6}}{2}$

$x=-1\pm \sqrt{6}i$

4x^2 - 9y^6 what patterns can be used ? please and thank you !!!

S_A_V [24]

Answer:

B. (U+V)(U-V)

Step-by-step explanation:

Factoring

The given expression is:

$4x^2-9y^6$

It should be noted that both terms are perfect squares:

$(2x)^2=4x^2$

$(3y^3)^2=9y^6$

Since it's a difference of squares, we need to use the following pattern to factor the required expression:

$(U^2-V^2)=(U+V)(U-V)$

Thus, the answer is

B. (U+V)(U-V)

Need help please. Thanks in advance

3x+4=10
Subtract 4 from both sides
3x=6
Divide both sides by 3
X=2

Sides = 10,10,5

Problem 5. 4x+1=29
Subtract 1 from both sides
4x=28
X=7
