Question

I will mark you as brainliest if you will give correct answer

Factorise
7+10(x+y)-8(y+y)^2

Answer 1

hi friend ,here is your answer

Factorisation of an algebraic expression is similar to finding factors of real numbers the only difference here is we use identities instead of prime numbers. Factoring algebraic expressions seem tricky, but with apt knowledge of identities, it becomes easy and fast. Let’s see how?

In an algebraic expression, while factoring, terms are formed as products of factors. For example, in the algebraic expression 7xy+3, The term 7xy has been formed by the factors 7, x and y, i.e., 7xy = 7×x×yHere we observe that the factors 7, x and y of 7xy cannot further be expressed as a product of factors. While factoring algebraic expressions the “prime” word is replaced by “irreducible”, therefore we may also say that 7, x and y are the prime factors or the irreducible forms of 7xy.
