Question

What should be the value of k if 7 Y squared-3 Y - k = 35 and Y = - 2

Answer 1

Heya !!!




Y = -2 [ Given ]




And,





7Y² - 3Y - K = 35 ------------(1)




Putting the value of Y in equation (1)





7 × (-2)² - 3 × -2 - K = 35




7 × 4 + 6 - K = 35




28 + 6 - K = 35





-K = 35 - 34



-K = 1




K = -1
