Using factorization, the factors of 2 x²+x-28 are x = - 4 and x = 7/2
The factorization approach simplifies any algebraic or quadratic equation by using the fundamental factorization formula, which represents the equations as the product of factors rather than extending the brackets. Any equation may have an integer, a variable, or the algebraic expression itself as a component.
Given equation is -
2 x²+x-28
we will use the method of factorization.
⇒ 2x² + 8x -7x -28
⇒ 2x(x+4) - 7(x+4)
⇒ (x+4) (2x - 7)
⇒ x = -4 and x = 7/2
