Question

which of the following expression have(x-3)(x+4) as factors​

Answer 1

Answer:

(x-3) (x +4) = x2 + (x+y) x+ (x×y)

Step-by-step explanation:

x2+ (-3+4) x+ (3×4) = x2+ (1x) + 12= x2 + +1x+12

Answer 2

The equation x²+4x-12 have the (x-3)(x+4) as factors​.

Explanation:

Given:

Roots of the equation : (x-3)(x+4)

To find:

The equation

Solution:

==> We know that, the format of the equation x²+x+c

==> (x-3)(x+4)

==> Multiply both the factors

==> x(x+4)-3(x+4)

==> x²+4x-3x-12

==> x²+4x-12

The equation x²+4x-12 have the (x-3)(x+4) as factors​.
