for what values of x is x² - 36 = 5x true?\n-9 and -4\n-4 and 9\n4 and -9\n9 and 4

Answer

Explanation:

Step1: Rearrange to quadratic form

$x^{2}-5x - 36=0$

Step2: Factor the quadratic

$(x - 9)(x + 4)=0$

Step3: Solve for x

Set each factor equal to zero: $x - 9=0$ gives $x = 9$; $x+4 = 0$ gives $x=-4$

Answer:

B. -4 and 9
