After manipulating above equation we get, 2x^2 - 7x - 8= 0. Discriminant= b^2 - 4ac = (-7)^2 - 4(2)(-8) = 113>0. So there are 2 real roots :)
Answer:
Step-by-step explanation:
The standard form of a linear equation is 
, where 
, 
, and 
are constants in the equation.
Based on the equation you have provided, the standard form would be 
, where 
.
To find the y-intercept, set 
.
Therefore, the y-intercept is 
.
Do the same thing for the x-intercept, but this time with 
.
Therefore, the x-intercept is 
.
Answer:
1. A sound wave in air has a frequency of 262 Hz and travels at a speed of 330 m/s.
2. Sound has a speed of 340 m/s in air at room temperature.
3. A wave has a frequency of 500 Hz and a wavelength of
4. The speed of light is 3.0x10^8 m/s, calculate for the frequency.

Answer:
(x + 2)²(x - 3)² = 0
Step-by-step explanation:
Since we have a degree of 2 and double of the same roots, we know that each root would have a multiplicity of 2. Therefore, our answer is(x + 2)²(x - 3)² = 0
