Factorise x^2-4x-50 |
|
Answer» Answer: hey! = Add 50 to both side of the equation : x2-4x = 50 Now the clever bit: TAKE the coefficient of x , which is 4 , divide by two, giving 2 , and FINALLY SQUARE it giving 4 Add 4 to both sides of the equation : On the right hand side we have : 50 + 4 or, (50/1)+(4/1) The common DENOMINATOR of the two fractions is 1 Adding (50/1)+(4/1) gives 54/1 So adding to both sides we finally get : x2-4x+4 = 54 hope it will be helpful ✌️ |
