Answer:
0.6 x 25 = x
Step-by-step explanation:
60% of 25
= 60/100 x 25
= 0.6 x 25
= 15
Though the question states as in a "select-all question," Only answer 0.6 x 25 = x will be correct.
Solve by using the quadratic formula.
x=1+-i√5 / 6
You have to factor this...
So you have started with this...
x²-x-2=0
If you factor this you will get
(x+1)(x-2)=0
This gives you two solutions...
x=-1, x=2
Hope this helps! Give me a five-rate and a thanks!
Yes silicon was made 1495 and its very useful
Factorise x^2+6x+8=0 to get (x+4)(x+2)=0
Solve to get x=-4, x=-2
Factorise x^2+6x+13=0 (I assumed you mistyped and wrote * instead of +)
Use the quadratic formula and you find that there are no real roots so the answer for this is just x=-4, x=-2
Tell me if I made any mistakes
