Question

4nsquare+5n-636 find roots by quadratic formula

Answer 1

Solution for 4n^2-5n-636=0 equation:==


Simplifying 4n2 + -5n + -636 = 0 Reorder the terms: -636 + -5n + 4n2 = 0 Solving -636 + -5n + 4n2 = 0 Solving for variable 'n'. Factor a trinomial. (-12 + -1n)(53 + -4n) = 0

Subproblem 1==

Set the factor '(-12 + -1n)' equal to zero and attempt to solve: Simplifying -12 + -1n = 0 Solving -12 + -1n = 0 Move all terms containing n to the left, all other terms to the right. Add '12' to each side of the equation. -12 + 12 + -1n = 0 + 12 Combine like terms: -12 + 12 = 0 0 + -1n = 0 + 12 -1n = 0 + 12 Combine like terms: 0 + 12 = 12 -1n = 12 Divide each side by '-1'. n = -12 Simplifying n = -12

Subproblem 2==

Set the factor '(53 + -4n)' equal to zero and attempt to solve: Simplifying 53 + -4n = 0 Solving 53 + -4n = 0 Move all terms containing n to the left, all other terms to the right. Add '-53' to each side of the equation. 53 + -53 + -4n = 0 + -53 Combine like terms: 53 + -53 = 0 0 + -4n = 0 + -53 -4n = 0 + -53 Combine like terms: 0 + -53 = -53 -4n = -53 Divide each side by '-4'. n = 13.25 Simplifying n = 13.25

Solution ==

n = {-12, 13.25}
