Evaluate (2x^2+3x-7)*(3x^2-5x+4)​

Answer»

<P>Answer:

\bf{ \boxed{ \bold{6x^<klux>4</klux>-x^3-28x^{2} +47x-28}}}

Step-by-step explanation:

(2x²+3x−7)(3x²−5x+4)

→ (2x²)(3x²)+(2x²)(−5x)+(2x²)(4)+(3x)(3x²)+(3x)(−5x)+(3x)(4)+(−7)(3x²)+(−7)(−5x)+(−7)(4)

→ 6x⁴−10x³+8x²+9x³−15x²+12x−21x²+35x−28

→ 6x⁴−x³−28x²+47x−28

You need to know that :-

  • Polynomials : Polynomial are variable based dialect in the language of maths.

  • In a common language , polynomials are defined as a STRING of variables and numbers put together.

  • Highest power of a polynomial is called degree of polynomial.

  • A constant polynomial is nothing but a monomial with degree zero.

  • Equation: A condition or a constraint placed on x and y coordinates.

  • Curve: A union of points that satisfy a particular condition.

  • Remainder THEOREM: When p(x) is DIVIDED by (x - a) then the remainder is given by p(a).
