adjacent=5 ,hypotenuse13 opposite=?

hypotenuse^2=opposite^2+adjacent^2

13^2=opposite^2+5^2

169-25=opposite^2

$\sqrt144$ =opposite

12=opposite

SinA=opposite/hypotenuse

Solve by completing the square p^2 +10p - 3 = 0

Mrac [35]

Solving $p^2 +10p - 3 = 0$ by completing the square method we get $(p+5)^2-28=0$

Step-by-step explanation:

We need to solve by completing the square method.

We are given: $p^2 +10p - 3 = 0$

The Completing square method is: (a+b)^2 = a^2+2ab+b^2

Solving:

$p^2 +10p - 3 = 0\\For \,\,making\,\,perfect\,\,square\,\,we\,\,add\,\,and\,\,subtract\,\,(5)^2\\p^2+2(p)(5)^2+(5)^2-3-(5)^2=0\\(p+5)^2-3-25=0\\(p+5)^2-28=0$

Solving $p^2 +10p - 3 = 0$ by completing the square method we get $(p+5)^2-28=0$
