Factor: x2 – 49 49 = 0 Don't put any space between the two binomials

Sagot :

The factors of the expression x^2 - 49 = 0 are as follows

(x + 7) (x - 7) = 0

The number 49 is a perfect square, and therefore the roots are either a negative 7 or a positive 7.

So the factores would be x + 7 or x - 7. That is,

When x + 7 = 0

Then x = -7

When x - 7 = 0

Then x = 7

The factors of the expression therefore are

(x + 7) and (x - 7)
