We rewrite the terms as (40 – 6) (40 + 3) and utilize the standard quadratic expansion identity. Computing the numerical components yields the final plain text answer.
We express the product as (20 – 2) (30 – 1) and expand using the distributive property. Evaluating the separate numerical products step by step gives the clean final total.
We split the middle term 7x into 3x plus 4x. Factoring the expressions in pairs gives the two linear binomial factors which are (2x + 1) and (3x + 2).
We split the middle coefficient minus 11 into minus 3 and minus 8 because their sum equals minus 11 and their product equals positive 24. This gives the factors directly.
