Answer:

Factorized

      =(2x-8)(x-3)

Roots : 4 , 3

Step-by-step explanation:

If it is to factorize :

2x^2 - 14x + 24 = 2x^2 -6x-8x +24

                     =2x(x-3)-8(x-3)\\=(2x-8)(x-3)

If it is to solve for x :

2x^2 -1 4x + 24 = 0\\(2x-8)(x-3)=0\\2x - 8 = 0 \ , \ x - 3 = 0\\2x = 8 \ , \ x = 3\\x = 4 , 3

What’s the answer to this?
Elina [12.6K]

Step-by-step explanation:

Line is passing through the points:

(-2,\:3)=(x_1,\:y_1) \:\&\: (2,\:5)=(x_2 ,\:y_2)

Equation of line in two point form is given as:

\frac{y -y_1 }{y_1 -y_2 } = \frac{x -x_1 }{x_1 -x_2 } \\ \\ \therefore \frac{y -3}{ 3 -5} = \frac{x -(-2) }{-2 -2} \\ \\ \therefore \frac{y -3}{ - 2} = \frac{x -(-2) }{-4} \\ \\ \therefore \frac{y - 3}{1} = \frac{x +2}{2} \\ \\ \therefore \: y-3= \frac{x}{2} + \frac{2}{2} \\ \\\therefore \: y= \frac{x}{2} + 1 +3\\ \\ \huge \red{ \boxed{\therefore \: y= \frac{1}{2} \:x+ 4}}\\ is \: the \: required \: equation \: of \: line.

If there are 100 students in a Masters Degree program at OU, and there`s a 5% failure rate, how many students are left after 12
Leviafan [203]
5% fail
so 100-5=95% are left

percent means parts out of 100
95% of 100 is \frac{95}{100} times 100=95

95 students are left assuming that the 5% that fail fail within 12 months

(6u^2+5u^2v^2−3uv^2)−(4u^4+5u^2^v^2−5uv)
Aleksandr [31]

Answer:

-4u^{4}+6u^{2}-5uv-3uv^{2}

Step-by-step explanation:

When subtracting polynomials, first start with distributing the negative sign to the second polynomial:

6u^{2} + 5u^{2} v^{2}-3uv^{2}-4u^{4}-5u^{2}v^{2}+5uv

Simplify by combining like terms:

-4u^{4}+6u^{2}-5uv-3uv^{2}
