Re-arranging, x2 - 14x +49 = 0
Factorising, (x-2)(x-2) = 0, hence x=2.
It is: 7 times 7 equals 49
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)
If you mean how do you factor z2 + 50z + 49, since the coefficient of z2 is 1, you just have to figure out what two numbers when multiplied together give you 49 and when added together give you 50. That's obviously 49 and 1. So... z2 + 50z + 49 = (z + 49)(z + 1)
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].
x2 - 14x + 49 = (x - 7)2
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.
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.
