Question:-

Factories:- m² - 10m + 21

Solution:-

=> m² - 10m + 21 =0

Split into middle term

=> m² - 3m - 7m + 21 = 0

=> m( m - 3 ) - 7 ( m - 3 ) = 0

=> ( m - 7 ) ( m - 3 ) = 0

=> m - 7 = 0 and m - 3 = 0

=> m = 7 and m = 3

=> m = 7 and 3

About factorization

=> A “quadratic” is a polynomial that is written like

ax² + bx + c”, where “a”, “b”, and “c” are just numbers.

=> For an easy case of factoring, you can identify the two numbers that will not only multiply to equal the constant term “c” but also add up to equal “b,” the coefficient on the x-term.

=> Factorising formulas algebra is especially important when solving quadratic polynomial When reducing formulas we normally have to remove all the brackets, but in particular cases, for example with fractional formulas, sometimes we can use factorisation to shorten a formula.
