"Swear by" means to make an oath invoking someone or something as a witness

Explanation

1 meter = 39.370 inches (exactly, by definition).

Explanation

1 yard = 36 inches  

So,  

1 square yard = 36 in × 36 in = 1296 square inches

Explanation

1 foot = 12 inches, so  

1 inch = 1/12 feet = 0.0833 feet.

Explanation

1 foot = 0.3048 meters (exact value)

Rounded to 4 decimal places, this is approximately 0.3056 meters. 

Explanation

Explanation

Step 1: Multiply the coefficient of the first term by the constant term i.e. (6 x 1) = 6

Step 2: Find the two factors of 6  such that whose sum equals to the coefficient of the middle term, i.e. -5.

Thus, the factors are -3 and -2 as,

-3 × (-2) = 6 (Product)

-3 + (-2) = -5 (Sum)

The polynomial  after splitting the middle term by using the two factors, -3 and -2 can be written as

x² - 3x - 2x + 6 = 0    

x(x-3) -2(x-3) = 0

(x-3)(x-2) = 0
