Question

Multiply (x² – 3x + 7) by (2x + 3).​

Answer 1

Answer:

2x2 – 4x + 5 by x2 + 3x – 7

(2x2 – 4x + 5) × (x2 + 3x – 7)

2x2 (x2 + 3x -7) – 4x(x2 + 3x – 7) + 5(x2 + 3x -7)

2x4 + 6x3 – 14x2 – 4x3 – 12x2 + 28x + 5x2– 15x - 35

2x4 + 6x3 – 4x3 – 14x2 – 12x2 + 5x2 + 28x + 15x – 35

Answer 2

Answer:

(x² – 3x + 7) by (2x + 3).

= 2x(x² – 3x + 7) + 3(x² – 3x + 7)

= 2x(x² – 3x + 7) + 3(x² – 3x + 7)

= 2x³-6x²+14x+3x²-9x+21

= 2x³-3x²+5x+21 [Ans.]

So, that is your answer

I hope it may help you.
