Question

x²-12x-45=0 factorization method​

Answer 1

Answer:

Step-by-step explanation:

By doing this method , you should get 45 as a product and -12 as a sum of two numbers .

The factors are x= 15 and x= -3.

If the factors are equal to 0 then it is x= -15 and x=3

Answer 2

Answer:

x2-15x+3x-45=0

x(x-15)+3(x-15)=0

(x-15)(x+3)=0

x-15=0 or x+3=0

x=15 or x= -3

15 and -3 are the roots of equation.
