Question

(a+c)(a-c) при a = 0.2 c = -0.6

Answer 1

Аквадрат-с квадрат 0,2-(-0,6)=0,2+0,6=0,8

Answer 2

(а+с)(а-с) = а  квадрат - с  квадрат

(0.2*0.2 ) - (-0.6*-0.6)= 0.04-(0.36)=  -0.32

Answer 3

To evaluate the expression (a+c)(a-c) when a = 0.2 and c = -0.6, we substitute these values into the expression:

(0.2 + (-0.6))(0.2 - (-0.6))

Simplifying further:

(-0.4)(0.2 + 0.6)

(-0.4)(0.8)

-0.32

Therefore, when a = 0.2 and c = -0.6, the value of the expression (a+c)(a-c) is -0.32.
