Question

49 - 4а в 2 степени = 0

Answer 1

Решение в зависимости от условия:
$49-4a^2=0;\\\\ 4a^2=49;\\\\ a^2=\cfrac{49}{4};\\\\ a = \pm \cfrac{7}{2}.$

Либо 

$49 - (4a)^2=0;\\\\ 16a^2=49;\\\\ a^2=\cfrac{49}{16};\\\\ a = \pm \cfrac{7}{4}.$

Answer 2

49-4а²=0
4а²=49
а²=49/4
а=±7/2
а=±3,5

Answer 3

To solve the equation "49 - 4a^2 = 0," you can follow these steps:

Step 1: Write down the equation: 49 - 4a^2 = 0

Step 2: Move the constant term to the other side of the equation: 49 = 4a^2

Step 3: Divide both sides by 4: a^2 = 49/4

Step 4: Take the square root of both sides: a = ±√(49/4)

Step 5: Simplify the square root: a = ±√(49)/√(4)

Step 6: Evaluate the square root: a = ±7/2

So, the solutions to the equation are a = 7/2 and a = -7/2.
