Question

BEFORE FIVE MINUTES AGO I
GAVE THE SAME QUESTION LIKE THIS THE TWO PRSON WHO GIVE ME THE AMSWER
AND THE TWO ANSWERS ARE WRONG .
SO,CAN ANYBODY GIVE ME THE CORRECT.
I KNOW THE ANSWER BUT I DO NOT KNOW HOW TO DO THIS STEP BY STEP. PLEASE.​

Answer 1

2(5²+5×-3)+3-5×-3

2(25-15)+3+15

2(10)+18

20+18

38.......

1.hai mate substitute the values in their places...here ab means 5 ×-3 = -15

so it is 25-15 .......as our way +×- = -

5×5=25

here 3-5×-3 = 3____15

2.here the symbol is - × - = +

so it is 3+15

3.add the bracket numbers and multiply with 2 ....

so the answer is

38

Answer 2

Answer:

Value of Expression= 38

Explanation:

Given:

$2( {a}^{2} + ab) + 3 - ab$

Multiplying the bracket by 2 and opening the bracket, we get:

$2 {a}^{2} + 2ab + 3 - ab$

Subtracting ab from 2ab, we get:

$2 {a}^{2} + 3 + ab$

Substituting the value of a and b in the above equation, we get:

$2 \times {5}^{2} + 3 + (( - 3) \times 5)$

Multiplying and performing calculation, we get:

$50 + 3 - 15$

$38$

Answer is 38.
