This is a quadratic equation question which will have two answers: 2x2+42 = x2+13x 2x2-x2-13x+42 = 0 x2-13x+42 = 0 Factorising the equation gives you: (x-6)(x-7) = 0 Therefore: x = 6 or x = 7
The expression cannot be factorised.

They are equal. 7 squared is 7 x 7, which equals 49. 6 x 7 = 42, plus another 7 = 49.
It is (x+6)(x+7) when factored
2x - 13x + 42 = x +ax + b a + b = 2(x - 6.5x + 21) = 34 = a + b

(x - 6)(x - 7)
The solution follows A=42 42X42=1764 B=56 56X56=3136 sum of above=4900 (70X70=4900) Given you was looking for C and not C squared. Try A and B and doublecheck it for me.
42 + 42 = 84
42 and 42
It is: 38+4 = 42
