Question

Evaluate each of the following by using Identities.

95 x 96​

Answer 1

Answer:

9120

Step-by-step explanation:

95 x 96

= (100 -5)(100 - 4)

using identity  $(x + a) (x + b) = x^{2} + x (a + b) + ab$ where a = -5 and b = -4

= 100^2 + 100( -5 - 4) + ( -5 x -4)

= 10000 - 900 + 20

= 9100 + 20

= 9120

Answer 2

Answer:

9120

Step-by-step explanation:

(100-5)(100-4)=

${100}^{2} - 900 + 20$

using identity

$(x + a)(x + b) = {x}^{2} + (a + b)x + a \times b$

10000-900+20

9120
