Determine the type and number of solutions of 3x^2+6x+4=0

Mathematics

Step 1. Calculate the discriminant:
\Delta =  b^2 - 4ac

Step 2.
If \Delta>0, there are two solutions, both real numbers
If \Delta=0, there is only one solution, real number
If \Delta, there are two solutions, both complex numbers

In your case:
a=3, b=6, c=4
\Delta = 6^2 - 4 \cdot 3 \cdot 4 = -12

So you have two solutions, both complex numbers

I hope this helps you



3x^2+6x+4=0


a=3 b=6 c=4



disctirminant=b^2-4ac



disctirminant=6^2-4.3.4


disctirminant=36-48


disctirminant= -12


x1= -6+ square root of -12/2.3



x1= -6+2i square root of 3/6



x1= -3+i square root of 3/3


x2= -6-2i square root of 3/6


x2= -3-I square root of 3/3

Prove divisibility 45^45·15^15 by 75^30
Anuta_ua [19.1K]

Answer:

3^{75}

Step-by-step explanation:

We are asked to divide our given fraction: \frac{45^{45}*15^{15}}{75^{30}}.

We will simplify our division problem using rules of exponents.

Using product rule of exponents (a*b)^n=a^n*b^n we can write:

45^{45}=(3*15)^{45}=3^{45}*15^{45}

75^{30}=(5*15)^{30}=5^{30}*15^{30}

Substituting these values in our division problem we will get,

\frac{3^{45}*15^{45}*15^{15}}{5^{30}*15^{30}}

Using power rule of exponents a^m*a^n=a^{m+n} we will get,

\frac{3^{45}*15^{45+15}}{5^{30}*15^{30}}

\frac{3^{45}*15^{60}}{5^{30}*15^{30}}

Using quotient rule of exponent \frac{a^m}{a^n}=a^{m-n} we will get,

\frac{3^{45}*15^{60-30}}{5^{30}}

\frac{3^{45}*15^{30}}{5^{30}}

Using product rule of exponents (a*b)^n=a^n*b^n we will get,

\frac{3^{45}*(3*5)^{30}}{5^{30}}

\frac{3^{45}*3^{30}*5^{30}}{5^{30}}

Upon canceling out 5^{30} we will get,

3^{45}*3^{30}

Using power rule of exponents a^m*a^n=a^{m+n} we will get,

3^{45+30}

3^{75}

Therefore, our resulting quotient will be 3^{75}.

Please help asap im super confused<br> Which is the equation for BC?
Aloiza [94]
Points on BC:
(-5, 5) and (0,1)
Slope = (5-1)/(-5-0)
Slope = -4/5

y = mx + c
y = -4/5x + c

at point (0,1)
1 = -4/5(0) + c
c = 1

y = -4/5x + 1
5y = -4x + 5
4x + 5y = 5 (Answer D)
