Question

use the complete square method to transform the equation x^2+2x=13 into an equation of the form (x+a)^2=b, where a and b are real numbers.what are the values of a and b?

part 1:what is the value of a
part 2:what is the value of b

Answer 1

cotA +(1/cotA) = 2,1.If √3tanA= 3sinA cotA +(1/cotA) = 2,1.If √3tanA= 3sinA cotA +(1/cotA) = 2,[cot²A +(1/cot2²A)]. cotA +(1/cotA) = 2,[cot²A +(1/cot2²A)]. cotA +(1/cotA) = 2, cotA +(1/cotA) = 2,
