Step-by-step explanation:
x^2+14x+45=0
x^2+(9+5)x+45=0
x^2+9x+5x+45
x(x+9)+5(x+9)=0
(x+9)(x+5)=0
either x+9=0 Or,x+5=0
x+9=0
x=0-9
x=-9
x+5=0
x=0-5
x=-5
therefore x=-9,-5

Scientific notation is used to write really large numbers, or really small numbers using less digits. For example:
1. Earth's distance from the sun 150,000,000 kilometers. We can rewrite this in scientific notation as 1.5 x

2. The length of a skin cell is 0.00003 meters. We can rewrite this in scientific notation as 3.0 x

3. The world population is about 7,000,000,000. We can rewrite this in scientific notation as 7 x
