Antonia is factoring the polynomial, which has four terms. 7x3 – 21x2 + 5x  – 15 7x2(x  – 3) + 5(x  –3) which is the completely factored form of her polynomial?

The given polynomial is :

Factorizing it by taking common factor among two terms

→7 x²(x-3) + 5 (x-3)

Taking (x-3) , common between two terms of the above expression, then the given expression is reduced in the form of,

→(x-3)(7 x² +5)→→Completely factored form of polynomial

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
