No, unless "a" happens to be equal to 0, or to 1.
x = zero and x = 13.
Only if the value of x is zero
If x^2 = 0, x = 0 Only 0^2 can equal 0.
No, it equals 0. If you have nothing, and you multiply it by nothing, you still have nothing.
Sin squared is equal to 1 - cos squared.
what is 10 squared DOES NOT equal what?
-2 squared will be 4. Remember that two negative numbers multiplied will always result in a positive answer. Therefore, any number squared will be positive (except 0 where the result will be 0).
It is x = 0.
Yes. Except where sin x = 0, because then you would be dividing by zero so the quotient is undefined.
3 squared is equal to 9
This question can not be solved
Using the discriminant of b^2 -4ac = 0 the value of k works out as -2
Only when X or Y = 0 That is because (x + y) squared = x^2 + 2xy + y^2 x^2 + 2xy + y^2 = x^2 + y^2 when x or y = 0
(a + b)Â² = aÂ² + bÂ². If you expand the left side, you have aÂ² + 2ab + bÂ² = aÂ² + bÂ². Subtracting aÂ² and bÂ² from both sides, you have: 2ab = 0. So if either a=0 or b=0 the equation is satisfied.
x^2 + x = 0 x(x+1) = 0 x = 0 and x = -1
144 + 0
0 squared is 0. Zero times zero equals zero.
25 squared plus 49 squared is equal to 3,026.
The law of cosines with a right angle is just the pythagorean theorem. The cosine of 90 degrees is 0. That is why the hypotenuse squared is equal to the sum of both of the legs squared
a2 + a2 = 2a2
13 squared x 4 squared is equal to 2,704.
289 squared times 289 squared is equal to 6,975,757,441.
