Hi can you help me i can’t move forward if i skip this question.

What is the expression in factored form? 225x^2 - 144 a. 9(5x+4)^2 b. 9(5x-4)^2 c. 9(4x+5)(4x-5) d. 9(5x+4)(5x-4)

Rewrite the following quadratic functions in intercept or factored form. show your work. y = x^2 + 7x + 10

Iknow its nothing to do with education, but what type of thing should i wrote here? ? : ) its for mcdonald's btw.
