The solution of the given expression (x − 2)(x 10) = 13 are x=3 or x=-11. So the option A is correct.
A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.
(x-2)(x+10) = 13
Subtract 13 from both sides
x²+8x-20-13=13-13
x²+8x-33=0
Factorized
(x-3)(x+11)=0
x-3=0 or x+11= 0
x=3 or x=-11
Thus, The answer is A
