Answer:5x²+14x-3=0
5x²+15x-x-3=0
5x(x+3)-x-3=0
5x(x+3)-(x+3)=0
(X-3)×(5x-1)=0
X1= x-3=-3
X2=1/5
Answer:
x= 1/5 and x= -3 or (-3, 0) and (1/5, 0)
Step-by-step explanation:
I think the easiest way would be the snowflake method.
you have to find 2 numbers that would multiply to get -15, but add to get 14, which would be 15 and -1.
then you would have (5x-1)(5x+15)
5x+15 would simplify to: x+3
your equation would then be:
(5x-1)(x+3)
make both of those equal to "0", and solve for both.
5x-1=0 and x+3=0
