The value of a can be obtained by substituting 1 to the equation and equating p(1) = 0.

<span> p(x) = x2a - 3xa + 3x2 -1 </span>

<span>p(1) = a - 3a +3 -1 = 0</span>

<span>therefore a =1</span>

the equation now becomes p(x) = x2 - 3x + 3x2 -1

CAn you help me with ratios? Mrs. Sturkie mixed 3 quarts of blue paint and 2 quarts of red paint to make purple paint to her cla
fredd [130]
So as we already know the ratio is 3 quarts blue paint to 2 quarts red paint, also written as 3:2. if she only has 1 quart blue paint she will need half of a quart of red paint because the ratio has to remain the same amount. if you multiply one side then you must multiply the other. same goes with division. If she only has 1 quart of red paint then that shows she divided the 2 red by 2. There fore you would have to divided the 3 by 2 in order to get 1.5 which would then make the ratio 1.5:1

Solve equation by completing the square round to the nearest hundredth if necessary <br> X2-4x-=5
kipiarov [429]

Answer:

x=-1 and x=5

Step-by-step explanation:

we have

x^{2} -4x=5

Solve it by completing the square method

We take the coefficient of x that is -4, divide it by 2 and then square it

so

-\frac{4}{2}=-2

square it

(-2)^2 = 4

Adds 4 both sides

x^{2} -4x+4=5+4

Combine like terms right side

x^{2} -4x+4=9

Rewrite as perfect squares

(x-2)^{2}=9

take square root both sides

x-2=\pm3

x=2\pm3

therefore

x=2+3=5

x=2-3=-1
