Question

Given the expressions are equivalent (3x + 2)^2 - (mx^2 + 7) = 5x^2 + 12x - 3 2 - 3 What is the value of m?​

Answer 1

Answer:M=4

Step by step answer

9x^2-mx^2+12x-3=5x^2+12x-35

9x^2-mx^2+12x-3+3=5x^2+12x-35+3

9x^2-mx^2+12x=5x^2+12x-32

9x^2-mx^2+12x-12x=5x^2+12x-32-12x

9x^2-mx^2-5x^2=5x^2-32-5x^2

-mx^2+4x^2=-32

x^2(-m+4)=-32

M=4

Hope this helps (;
