Solution for (u+5)(u+5)=2u^2+u+43 equation:


Simplifying
(u + 5)(u + 5) = 2u2 + u + 43

Reorder the terms:
(5 + u)(u + 5) = 2u2 + u + 43

Reorder the terms:
(5 + u)(5 + u) = 2u2 + u + 43

Multiply (5 + u) * (5 + u)
(5(5 + u) + u(5 + u)) = 2u2 + u + 43
((5 * 5 + u * 5) + u(5 + u)) = 2u2 + u + 43
((25 + 5u) + u(5 + u)) = 2u2 + u + 43
(25 + 5u + (5 * u + u * u)) = 2u2 + u + 43
(25 + 5u + (5u + u2)) = 2u2 + u + 43

Combine like terms: 5u + 5u = 10u
(25 + 10u + u2) = 2u2 + u + 43

Reorder the terms:
25 + 10u + u2 = 43 + u + 2u2

Solving
25 + 10u + u2 = 43 + u + 2u2

Solving for variable 'u'.

Reorder the terms:
25 + -43 + 10u + -1u + u2 + -2u2 = 43 + u + 2u2 + -43 + -1u + -2u2

Combine like terms: 25 + -43 = -18
-18 + 10u + -1u + u2 + -2u2 = 43 + u + 2u2 + -43 + -1u + -2u2

Combine like terms: 10u + -1u = 9u
-18 + 9u + u2 + -2u2 = 43 + u + 2u2 + -43 + -1u + -2u2

Combine like terms: u2 + -2u2 = -1u2
-18 + 9u + -1u2 = 43 + u + 2u2 + -43 + -1u + -2u2

Reorder the terms:
-18 + 9u + -1u2 = 43 + -43 + u + -1u + 2u2 + -2u2

Combine like terms: 43 + -43 = 0
-18 + 9u + -1u2 = 0 + u + -1u + 2u2 + -2u2
-18 + 9u + -1u2 = u + -1u + 2u2 + -2u2

Combine like terms: u + -1u = 0
-18 + 9u + -1u2 = 0 + 2u2 + -2u2
-18 + 9u + -1u2 = 2u2 + -2u2

Combine like terms: 2u2 + -2u2 = 0
-18 + 9u + -1u2 = 0

Factor a trinomial.
