Re-arranging, x2 - 14x +49 = 0
Factorising, (x-2)(x-2) = 0, hence x=2.
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
49 - 30 equals = 19
It equals to .49
It is 72 = 49.
the answer is 98
343 divided by 49 equals 7.
343 divided by 7 equals 49
The number 7 raised to the 2nd power (or squared) equals 49.
