Answer:
x=2
Step-by-step explanation:
use distributive property: x^2+2x-1=4
remove the -1 by adding 1 on both sides: x^2+2x=5
use the guadratic fromula: ax²+bx+c=0
plug in the equation x^2+2x-5=0
a,b and c are the coefficients to plug into the formula
a=1, b=2, c=-1
Finally, you will find that x=2
Answer:
multiple and divide are depending on the powers ( sometimes the numbers before the scientific n.)
If the power neg- , it's going down
like this 10^-5 = 1/10^5
If the power pos+ , it's the same idea but different in signs .
Adding and subtracting are depending on numbers ( If the scientific n. is the same number) .
for example:
3x10^5 + 4x10^5 = (3+4)x10^5 = 7x10^5
