Find the roots of the equation: y=4(X+4)^2 -12

Dafna1 [17]

0=4(x²+8x+16)-12
0=4x²+32x+64-12
0=4x²+32x+52
0=x²+8x+13
D=b²-4ac
D=64-52=12
x=(-b-√D)/2a
x=(-b+√D)/2a
x=(-8-2√3)/2= (-2(4+√3))/2= -(4+√3)
AND
x=(-8+2√3)/2=-2(4-√3)/2= -(4-√3)

What is the following quotient?

Sergio039 [100]

Answer:

$\frac{\sqrt{3} }{4}$

Step-by-step explanation:

$\frac{1}{1+\sqrt{3} }$

basically we want to get rid of the √3 on the denominator

to do so we multiply it by itself so it is a perfect square

but whatever we do to the top we must do to the bottom so we multiply the numerator and denominator by √3

$\frac{1*\sqrt{3} }{1+\sqrt{3}*\sqrt{3} }=\frac{\sqrt{3} }{1+\sqrt{9} } =\frac{\sqrt{3} }{1+3} =\frac{\sqrt{3} }{4}$

notes : √3 × √3 = √9 which is a perfect square that simplfies to 3

{-4 1/2,-1,3/4,3.5,13,24 5/8 }<br> Are these all integers

dlinn [17]

Answer: No, not all of those numbers are integers.

Step-by-step explanation:

${-4\frac{1}{2}, -1, \frac{3}{4}, 3.5, 13, 24\frac{5}{8} }$

Integers are whole numbers (including zero) that are positive or negative. Integers cannot have fractions or decimals.

Therefore, only $-1$ and $13$ are integers, and ${-4\frac{1}{2}, \frac{3}{4}, 3.5, 24\frac{5}{8} }$ are not integers.
