Answer» ANSWER: x² - 7x - 30 = 0 x² - 10 x + 3x -30 =0 x(*x-10)* + 3(*x-10)* = 0 (*x-10)* (x+3) =0 *x-10* = 0 & x+3 = 0 => x = 10 & x = - 3 <= *hope* it helps you *mark* as brainliest

3) Determine which value is the rootof the quadratic equationx2-7X-30=0*

Answer»

ANSWER:

x² - 7x - 30 = 0

x² - 10 x + 3x -30 =0

x(x-10) + 3(x-10) = 0

(x-10) (x+3) =0

x-10 = 0 & x+3 = 0

=> x = 10 & x = - 3 <=
