2x2-12x-54 = 0 Solve by factoring or using the quadratic equation formula or by completing the square: (2x+6)(x-9) = 0 Therefore: x = -3 or x = 9
Yes. You must use the "slip and slide" factoring method because there is a 2 coefficient infront of x2. 2x2-12x-80 = (x-10)(2x+8)
Solve by factoring.2x2 - 3x + 1 = 0
(2x - 7)(x - 2)
Yes
2x2 equals 5
no
Yes, because 2x2 equals 4 and 4/2 equal 2
"Equals" means "the same as." eg 4 = 2x2; four is the same as 2x2. eg "I am your intellectual equal"; our intellects are the same.
3
2x2 = 4 , Four . 2x2 = 4 , Four .
I'm sorry but I can't solve that problem. B(
