Factorize x squared - 1x +10 =0
Natalka [10]

Answer:

no solution exists:

Step-by-step explanation:

x²−1x+10=0

Step 1: Simplify both sides of the equation.

x²−x+10=0

Step 2: Subtract 10 from both sides.

x²−x+10−10=0−10

x²−x=−10

Step 3: The coefficient of -x is -1. Let b=-1.

Then we need to add (b/2)^2=1/4 to both sides to complete the square.

Add 1/4 to both sides.

x²−x+ 1/4=−10+ 1/4

x²−x+ 1/4=−39 /4

Step 4: Factor left side.

(x  -1/2)² = −39 /4

Step 5: Take square root.

x  −1 /2 =±√ −39 /4

Step 6: Add 1/2 to both sides.

x  =−1/2  + 1/2 = 1/2 ±√ -39/4

x = 1/2 ±√ -39/4

No real solutions.

Find the value of x.
pogonyaev

1st image:

20 (20 + x) = 40^2

400 + 20x = 1600

20x = 1200

   x = 60

---------------

2nd image:

5 * x = 10 * 6

5x = 60

 x = 12

Rewrite the equation 7-y=5x+11 to standard form
Zielflug [23.3K]
Rewriting this <span>7-y=5x+11 in standard form involves only changing the order in which the terms appear:

</span><span>7-y=5x+11 becomes 5x + y  + 11 - 7 = 0, or 5x + y + 4 = 0, or 5x + y = -4.</span>
