What are the roots of the equation?

x2=5x+14
Enter your answers in the boxes.

x=
or x=

the roots of the equation are x = 7 and x = -2

Step-by-step explanation:

To do this we first have to take that equation to the following form

Ax^2 + Bx + C = 0

x^2=5x+14

x^2 - 5x - 14 = 0

A = 1

B = -5

C = -14

-b(+-)√(b^2 - 4ac) / 2a

- (-5) (+-)√((-5^2) - 4 * 1 * (-14) ) / 2 * 1

5 (+-) √(25 + 56) / 2

5 (+-) √81  /2

(5 (+-) 9) /2

x1 = (5 + 9) / 2

x1 = 14/2

x1 = 7

x2 = (5 - 9) / 2

x2 = -4 / 2

x2 = -2

answer: 25.4 units

step-by-step explanation: radius = 12.7 units

diameter = twice the radius

diameter = 12.7 x 2

= 25.4

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m

hope this : )
