Question

010. Factorise this no.
x2-41x -180 =0.​

Answer 1

Answer:

45 ; -4

Step-by-step explanation:

Given,

X^2 - 41x - 180= 0

Factories this given quadratic equation

X^2 -45x + 4x - 180 = 0

X(x - 45) + 4 ( x - 45) = 0

(X-45)(x+4)

Either,

X - 45 = 0

X = 0+45

X= 45

Or,

X+4 = 0

X = 0-4

X = -4

Answer : 45 ; -4
