Complete the square to solve 4x^2 + 24x = 4

dalvyx [7]

Answer:

4x^2+24x=4

Step 1:

make the coefficient of x² as 1, divide both sides by 4

x² +6x =1

Step 2:

take half of coefficient of x, square it and add it to both sides

half of 6 is 3 and 3²=9, so add 9 to both sides

x² +6x+9=1+9

x²+6x+3²=10

(x+3)²=10

now when we take square root we will get both + and - √10 on right side

x+3= +√10

x+3=-√10

solving for x

x=+√10-3

Can someone help me with this question.

Korolek [52]

Answer:

lesser x = -4

greater x = 1

Step-by-step explanation:

here's the solution :-

=》

${x}^{2} + 3x - 4 = 0$

=》

${x}^{2} + 4x - x - 4$

=》

$x(x + 4) - 1(x + 4)$

=》

$(x + 4)(x - 1)$

now, there are two cases

case 1) where x + 4 = 0

=》x = -4

case 2) where x - 1 = 0

=》x = 1

Question:

DanielleElmas [232]

Given A room is half as long again as it is broad

Let the breadth of the room x m

length of the room x + x/2 = 3x/2m

Area of the room , x × 3x/2 =<em> 3x²/2m</em>

Given , cost of carpeting the room at Rs. 3.25m⁻²

So , total cost , 3x²/2 × 3.25

But , Total cost of carpeting is given as 175.50 so ,

(3x²/2 )× 3.25 = 175.50
x² = 175.50 × 2 / 3.25 × 3
x² = 36
x = 6

Breadth x = 6 m
length 3x/2 = 9m

let the height of the room H m

Area of the four wall = 2(L+ b)× h 2(6+9)× H

= 30H m²

Area of the of the one door and two window is 8m²

8m² Area to be prepared = Area of four wall - area of two window and 1 door = (30H - 8) m²

Given cost of preparing wall is Rs. 1.40m²

total cost of preparing wall is (30H - 8) × 1.40

Total cost of preparing wall is given as 240.80

comparing , (30H - 8 ) × 1.40 = 240.80

(30H - 8 ) = 240.80 /1.40 = 172
30H -. 8 = 172
30H = 180
H = 180/30 = 6

Hence, Dimensions of the room are lengths 9m , breadth 6m and height 6m

Use the given conditions to write an equation for the line in point-slope form and general form. Passing through (7 , 9 )and pa

levacccp [35]

When the given line is in standard form or general form (as here), the desired line can be found by replacing the constant by zero, and then translating the line to the given point.

The starting point for your solution can be
7(x-7) - 5(y-9) = 0

In general form, this is
7x - 5y - 4 = 0

In point-slope form, this is
y - 9 = (7/5)(x - 7)
