Answers
Step-by-step explanation:
but I'm telling you how do this sum first we say you have the statement 4 x square minus x minus 4 so this statement is called the quadratic equation so firstly you have to see the first term and the last term you have to multiply the first term and the last term now as example 4 x square minus multiply with the -4 so you got 16 x square fine now see the middle term your middle term is minus x here is not term used with the minus x no constant variable used with the - x it mean you have to do as taken as 1 x ok so now you have to say like for the 16 now you have to see what I should take the two numbers which are addition or maybe subtraction by the one ok so I can't find that number otherwise I can't find your some sorry
