x2+2x = 7
Completing the square:-
(x+1)2 = 7
(x+1)2-1 = 7
(x+1)2 = 8
x+1 = -/+ sq rt 8
x = -1-/+ sq rt 8
12 squared.
Solve this problem -x squared -40x- 80 =0
Your Problem: X - 4 = ?Current Problem: 3 [squared] - 4 = ?How: When a numbered is squared, it means you multiply it against itself. So, 3 squared equals 3x3.3x3 = 9So, you would then take 9 and minus it by 4, which would than equal 5.Answer:3 [squared] - 4 = 5or9 - 4 = 5
Cut the diameter in half.
Since a squared plus b squared equals c squared, that is the same as c equals the square root of a squared plus b squared. This can be taken into squaring and square roots to infinity and still equal c, as long as there is the same number of squaring and square roots in the problem. Since this question asks for a and b squared three times, and also three square roots of a and b both, they equal c. Basically, they cancel each other out.
5.477225575 squared equals 30.
The number that equals 121 when squared is 11.
b = sqrt32 or 4 root 2
No, it equals -2xy. lrn2math
It cannot be solved because the discriminant of the quadratic equation is less than zero
