Question

Verify :
$a \times (b + c) = (a \times b) + (a \times c)$
$if \ \: a = - 3 \: .b = 7.c = - 9$
it's urgent ​

Answer 1

a*(b+c) = (a*b) + (a*c)

Left hand side.

a*(b+c)

= -3*(7+(-9)

= -3*(-2)

= 6

Right hand side

(a*b) + (a*c)

= (-3*7) + (-3*(-9)

= (-21) + (27)

= 6

Hence, verified
