Solve the followi

Answer :

In factorization, we write the middle term of the quadratic equation either as a sum of two numbers or difference of two numbers such that the equation can be factorized.



30(x – 7 – x – 4) = 11(x + 4)(x – 7)


-330 = 11x2 – 308 – 33x


11x2 – 33x + 22 = 0


x2 – 3x + 2 = 0


x2 – 2x – x + 2 = 0


x(x – 2) – (x – 2) = 0


(x – 1)(x – 2) = 0


x = 1, 2
