Question

Determine the type and number of solutions of x^2 + 10x − 25 = 0. A two real solutions B one real solution C two imaginary solutions

Answer 1

two real solution

Explanation:

x^2 + 10x − 25 = 0

we can solve this by finding out the value of x

lets assume the equation is a\times x^{2}+b\times x+c=0

x=-b\pm \sqrt{(b^{2}-4ac)}\div 2a

x=-10\pm\sqrt{100+4*25}\div2

x=-5\pm5\sqrt2

then we get both real value of x

so two real solution
