Re-arranging, x2 - 14x +49 = 0
Factorising, (x-2)(x-2) = 0, hence x=2.
It is: 7 times 7 equals 49
One-seventh of 49 is 7. This is calculated by dividing 49 by 7, which equals 7.
49 x 7
49 does not go into 189 evenly. 189 divided by 49 equals 3 with a remainder of 42.
16x2 - 49 = 42x2 - 72 = (4x)2 - 72 = (4x - 7)(4x + 7)
252-70x+49 = (5x-7)(5x-7) when factored
x2 - 14x = -49 ∴ x2 - 14x + 49 = 0 ∴ (x - 7)2 = 0 ∴ x = 7
45+4 = 49 49/7=7 7*7=49-4=45 so x=7
for the equation: -2h² - 28h - 98 = 0 can be factored as follows: -2(h² + 14h + 49) = 0;to solve, the expression in parenthesis must equal zero: (h² + 14h + 49) = 0. We are looking for values, which when added equal 14, and when multiplied equal 49.(h + a)(h + b) = 0, where we want a+b = 14, and ab = 49. The answer is a = 7 and b = 7, so we have (h + 7)(h + 7) = 0, and h = -7,-7 [double root].
To solve the equation (X^2 + 14X + 49 = 0), you can factor it as ((X + 7)^2 = 0). Setting this equal to zero gives (X + 7 = 0), leading to the solution (X = -7). Alternatively, you could use the quadratic formula, but in this case, factoring is simpler.
x2 - 14x + 49 = (x - 7)2
49 - 30 equals = 19
To find the number that, when multiplied by 7, equals 49, you can divide 49 by 7. Doing the calculation, 49 divided by 7 equals 7. Therefore, 7 times 7 equals 49.
The number that equals the 2nd power of 49 is the square root of 49. In this case, the square root of 49 is 7, because 7 multiplied by itself (7^2) equals 49. Therefore, the number that equals the 2nd power of 49 is 7.
the answer is 98
It is 72 = 49.
343 divided by 49 equals 7.
