<em>Step #1: </em>
Make sure the equation is in the form of [ Ax² + Bx + C = 0 ].
Yours is already in that form.
A = 1
B = 2
C = -2
<em>Step #2:</em>
The 'discriminant' for that equation is [ B² - 4 A C ].
That's all there is to it, but it can tell you a lot about the roots of the equation.
-- If the discriminant is zero, then the left side of the equation is a perfect square,
and both roots are equal.
-- If the discriminant is greater than zero, the the roots are real and not equal.
-- If the discriminant is less than zero, then the roots are complex numbers.
The discriminant of your equation is [ B² - 4 A C ] = 2² - 4(1)(-2) = 4 + 8 = 12
Your equation has two real, unequal roots.
the answer is that it is false
Answer: 96
Step-by-step explanation:
3/5 block mile is also 0.6 block mile
4 1/2 miles is also 4.5 miles
How many 0.6mi blocks do you run to run 4.5 miles?
4.5miles/0.6block mi = 7.5 or 7 1/2 blocks will equal 4.5 or 4 1/2 miles.
Check 7.5 blocks x 0.6 block mi = 4.5 miles
Same as you know one quarter equals $0.25 cent. And how many do you need to make one dollar that equals $1.00 ?
1/ .25 = 4 quarters
