Which expression is not equivalent to (x + 4)(x – 3)?

Digiron [165]

Answer:

A) x² + 7x - 12 is NOT equivalent to the expression.

Step-by-step explanation:

1) expand by distributing terms.

${x }^{2} - 3x + 4(x - 3)$

2) Expand by distributing terms.

${x}^{2} - 3x + 4x - 12$

3) Collect like terms.

${x}^{2} + ( - 3x + 4x) - 12$

4) Simplify.

${x}^{2} + x - 12$

The second equation are equivalent to the equation. but the first equation is not equivalent to the main equation.

Write z in polar form:

z = 1 + √3 i = 2 exp(i π/3)

Taking the square root gives two possible complex numbers,

√z = √2 exp(i (π/3 + 2kπ)/2)

with k = 0 and k = 1, so that

√z = √2 exp(i π/6) = √(3/2) + √(1/2) i

and

√z = √2 exp(i 7π/6) = -√(3/2) - √(1/2) i
