What are the solutions to the equation?

3x^2+6x=45

enter your answers in the boxes.

Step-by-step explanation:

3x² +6x = 45

divid by : 3 :

x² +2x = 15

(x² +2x +1 )-16 = 0

( x + 1 )² - 4² = 0

note : a² - b² = (a - b ) ( a + b)  ...idetity

( x +1 -4)( x + 1 +4) = 0

(x -3 ) ( x+5) =0

x-3 = 0 or x +5 = 0

x = 3  or x = - 5

my answer in the boxes :   x = 3 and x = -5

in mathematics, a function is a relationship between two variables such that the value of one of the variables, called the dependent variable, is determined by the value of the other variable, called the independent variable. there is a specific term we use to describe the set of independent variables of a function.
