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 $(p+5)^2-28=0$

A car travels 1.9 miles from Point A to Point B. The car then turns at Point B and travels 1 mile to Point C, before heading bac

tamaranim1 [39]

If you represent the problem in a diagram, you will form a triangle with 3 known length of the sides. When you are given all sides, and you are asked to find an angle, you can use the cosine law.

b^2 = a^2 + c^2 - 2ac*cosB
1.4^2 = 1.9^2 + 1^2 - 2(1.9*1)(cosB)
B = 45.78°
