<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.
Answer:
4x^2-7x+3
Step-by-step explanation:
(4x-3)(x-1)
4x^2-4x-3x+3
4x^2-7x+3
Answer:
Step-by-step explanation:
with a 45-45-90 triangle the hypotenuse is equal to the length of one of the legs times the square root of 2.
if one of the legs is 1.2 than the hypotenuse of this triangle should be
1.2* sqrt(2) = about 1.7
The answer is C.
C is the only answer that doesn’t name an animal that has 4 legs.
