Plz explain me in simplest way. after x2 +17x-60=0 , i couldn't understand.

see explanation

Step-by-step explanation:

Given

x² + 17x - 60 = 0

To factor the quadratic

Consider the factors of the constant term (- 60) which sum to give the coefficient of the x- term (+ 17)

The factors are + 20 and - 3, since

product = + 20 × - 3 = - 60 and sum = + 20 - 3 = + 17, thus

x² + 17x - 60 = (x + 20)(x - 3) = 0

Equate each factor to zero and solve for x

x + 20 = 0 ⇒ x = - 20

x - 3 = 0 ⇒ x = 3

-60.75

step-by-step explanation:

just add the numbers then put the negative sign on it

a. (14,375+570)(5.3) b. 158,417$

step-by-step explanation:

a. you are basically just setting up the equation. f= amount of debt hence 14,375. g= how much she is borrowing from her parents weekly hence 570 and t= the interest on her debt. creating the equation.

b.   14,375+570= 14,945

      14,945 x 5.3 = 79,208.5

      79,208.5 x 2(years) = 158,417(answer)
