Kiran and Mai are trying to figure out if this equation is an identity, what do you think

ValentinkaMS [17]

Expanding the left side of the equation, it is found that since both sides are equal, yes, it is an identity.

An equality represents an identity if both sides are equal.

In this problem:

$(a - b)^4 = a^4 - 4a^3b + 6a^2b^2 - 4ab^3 + b^4$

Expanding the left side:

$(a - b)^2(a - b)^2 = a^4 - 4a^3b + 6a^2b^2 + 4ab^3 + b^4$

$(a^2 - 2ab + b^2)(a^2 - 2ab + b^2) = a^4 - 4a^3b + 6a^2b^2 - 4ab^3 + b^4$

$a^4 - 4a^3b + + 6a^2b^2 - 4ab^3 + b^4 = a^4 - 4a^3b + 6a^2b^2 - 4ab^3 + b^4$

Since both sides are equal, yes, it is an identity.

How can I solve this question

Lapatulllka [165]

Answer:

The value of x can be 5 or 2

Step-by-step explanation:

In given triangle ABC

Interior Angle A = $x^{2} +3x+20$

Interior Angle B = $x^{2} +14x-5$

Exterior Angle I = $3x^{2} +10x+25$

We know that

Exterior Angle of triangle is summation of corresponding opposite angles

Angle I = Angle A + Angle B

$3x^{2} +10x+25= (x^{2} +3x+20)+(x^{2} +14x-5)$

$3x^{2} +10x+25= 2x^{2} +17x+15$

$1x^{2}-7x+10=0$

$x^{2}-2x-5x+10=0$

$x(x-2)-5(x-2)=0$

$(x-5)(x-2)=0$
