What is a quadratic equation?
An algebraic equation of the second degree in x is a quadratic equation. The quadratic equation is written as ax2 + bx + c = 0, where x is the variable, and a must not be zero.
For example 3x² + 6x + 8 = 0 here x has heighest term as 3 and coefficient of x² is not zero
Given that,
(x + 7)(3x − 8)
⇒ x(3x − 8) + 7(3x − 8)
⇒ 3x² - 8x + 21x - 56
⇒ 3x² + 13x - 56
Hence it will be the simplest form of this expression.
