Question

please factorize!! split the middle term​

Answer 1

Answer:

The factors are (x + 3)(7x - 30).

Step-by-step explanation:

The expression is: 7x² - 9x - 90 = 0.

Factorize the expression as follows:

$7x^{2}-9x-90=0\\7x^{2}+21x-30x-90=0\\7x(x+3)-30(x+3)=0\\(x+3)(7x-30)=0$

Thus, the factors are (x + 3)(7x - 30).
