Answer:

x=\pm2

Step-by-step explanation:

The given equation is

x^2-14=-10

Add 14 to both sides of the equation.

x^2=-10+14\\\\x^2=4

Now, take square root both sides. Whenever, we take square root both sides, we include plus minus sign

\sqrt{x^2}=\pm\sqrt{4}

On simplifying, we get

x=\pm2

X^2 - 14 = -10
x^2 = -10 + 14
x^2 = 4....take the square root of both sides, eliminating the ^2
x = (+-) sqrt 4
x = 2 and x = -2

The area of a rectangular
tankabanditka [31]

Answer:

2x+5

Step-by-step explanation:

Okay so lets first factor 2x^2+15x+25

2*25=50

10+5=15

10*5=15

(x+10/2)(x+5/2)

=(x+5)(2x+5)

we know that the width is x+5 so that means the length has to be 2x+5
