Question

Which of the following expressions has the same value as 4(x+3)2? A. 12(4x+3) B. 12x2 C. 4x+23 D. 12(4x+12)

Answer 1

3x^2−4x+3 = x^2+x+1 2x^2−4x+3 = x+1        _________subtracingt x^2 from both sides 2x^2−5x+3 = 1            _________subtracingt x from both sides 2x^2−5x+2 = 0             _________subtracingt 1 from both sides (x-2)(x-1/2)=0             _________ factoring the equation x=2 or x=1/2
there u go

Answer 2

Answer with explanation:

The expression whose Identical expression we have to find is:

  $4 \times (x+3)^2=4 \times (x^2+6 x+9)\\\\=4 x^2+4 \times 6 x+4 \times 9\\\\=4 x^2+24 x+36$

----------[Using distributive property of multiplication with respect to Addition]

Used the Identity

⇒(a+b)²=a²+2 a b+b²

None of the option
