Question

x2=17x+60.find the value of x

Answer 1

x^2 = 17x + 60

x^2 - 17x - 60 = 0

x^2 - 20x + 3x - 60 = 0

x (x - 20) + 3 (x - 20) = 0

(x + 3) (x - 20) = 0

x + 3 = 0 and x - 20 = 0

Ans. the value of x = - 3 and 20

Answer 2

Hello,

Here's the answer :-

x^2 = 17x + 60

=> x^2 - 17x -60 = 0

=> x^2 -20x + 3x -60 = 0

=> x(x -20) + 3(x-20) = 0

=> (x+3)(x-20) = 0

When x+3 = 0

=> x = -3

When x-20 = 0

=> x = 20

So, x = -3 or 20

Hope it helped :-)
