x2 + 49 = 0 ∴ x2 = -49 ∴ x = 7i
Yes
To calculate the sum of 49 plus 49 plus 49 plus 49 plus 49, you would multiply 49 by 5, which equals 245. This is because addition is a form of repeated multiplication. So, 49 multiplied by 5 is 245.
x2 + y - 49 = 0At the x-intercepts, y=0:x2 - 49 = 0(x+7)(x-7) = 0x = -7 and x = +7At the y-intercept, x=0:y - 49 = 0y = 49

If by w2 you mean "w squared", then it cannot be done. BECAUSE w2 + 49 = 0 w2 +49 - 49 = 0 - 49 w2 = -49 w2 means a number multiplied by itself. Any number multplied by itself will result in a POSITIVE number. positive x positive = positive negative x negative = negatve
ax2 + bx + c = 0 x2 + 14x + 49 = 0 Figure out what two numbers can be multiplied to get the sum of a + c and can be added together to equal b. 7 * 7 = 49 7 + 7 = 14 (x + 7)(x + 7) = 0 Solve each for x: x + 7 = 0 x = -7 x + 7 = 0 x = -7
If there are no parenthesis then -9+9/7*7=0 as 0/49 =0
+49 is the code for Germany, it's not the code for any german city. +49 (0) 30 would be the code for Berlin.
