^ = power to
can u answer this now please its urgent i only got 2 mars how do i get the other 2 marks and the bottom bit of the question got me 2 marks thew top bit didnt get me anything

Answer 1

x = 11 / x = - 4

Explanation:

x² - 7x - 34 = 10

x² - 7x - 34 - 10 = 10 - 10

x² - 7x - 44 = 0

x² + 4x - 11x - 44 = 0

x (x + 4) - 11 ( x + 4) = 0

(x - 11)(x + 4) = 0

(x - 11) = 0 / (x + 4) = 0

x = 11 / x = - 4

Hope that helps! (If it doesn't, please tell me what you want me to answer or explain, or how I can improve the answer.) :)
