Question

Find the value of (a - b) (2a? - 3ab + b) when a = 3 and b = 2.​

Answer 1

Answer:-10

Step-by-step explanation:

(a-b) (2a-3ab+b) when a=3&b=2

=(3-2)×(2(3)-3(3*2)+2)

=1*(-10)

=-10

Answer 2

Value of (a - b) (2a - 3ab + b) = -10

GIVEN:- a = 3 and b= 2

TO FIND:- (a - b) (2a - 3ab + b)

SOLUTION:-

• Substitution means replacing the variables in an algebraic expression with their values in numbers

According to the question we need to substitute the values of a and b in the equation (a - b) (2a - 3ab + b)

$(a - b) (2a- 3ab + b) \\ = (3 - 2)(2 \times 3 - 3 \times 3 \times 2 + 2) \\ = 1(6 - 18 + 2) \\ = 6 - 18 + 2 \\ = - 10$

Hence, the Value of (a - b) (2a - 3ab + b) = -10
