How would you factorise x^2 + 4x + 4

This is in the form ax2 + bx + cWhere, a= 1b=4c=4To factor we have to find two numbers that:Add up to b, in this case 4Multiply together to give c, in this case also 4So we deduce that the two numbers are +4 and +4 as;2 + 2 = 4, b2 x 2 = 4, c Therefore the factorised form is:(x+2)(x+2)As both the brackets are the same We can express this as (x+2)2
