Answer:
x = 4
x = 10
Step-by-step explanation:
x^2 -14x + 40 = 0 ----> factor form
(x - 10)(x - 4) = 0 ---> separate equations
x - 10 = 0 ---> add 10 on both sides
x - 4 = 0 ---> add 4 on both sides
small x= 4
large x= 10
hello there!
x^2-14x+40=0
x^2-(10+4)x+40=0
x^2-10x-4x+40=0
pick out the common one!
x(x-10)-4(x-10)=0
(x-10)(x-4)=0
now;
x-10=0
x=10(which is large x)
again:
x-4=0
x=4( which is small x)
hope it helps.. thank u!
