Rewrite the equation by completing the square.
2 x^{2} -9 x +7 = 0

(x+blank )^2=blank

Rewrite the equation by completing the square:

Solution:

Given that,

We have to rewrite by completing the square

Step 1:

The general quadratic equation is given as:

Compare with given, we get,

a = 2

b = -9

c = 7

Step 2:

From given,

Subtract 7 from both sides,

Step 3:

Find square of half of b

Add the term to each side of equation

Simplify

The left side is of form:

Therefore,

Thus the solution is found

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.

i dont know if you cant find a way its best to actually add all of them start from 105 tho
