Which product is equivalent to 25x2 – 16?

Genrish500 [490]

ANSWER
$25 {x}^{2} - 16 =( {5x - 4})(5x + 4)$

EXPLANATION

We want to factor the expression,

$25 {x}^{2} - 16$

We can rewrite the expression as

$25 {x}^{2} - 16 = ({5x})^{2} - {4}^{2}$

The expression is now a difference of two squares,

Recall that,

${a}^{2} - {b}^{2} = (a - b)(a + b)$

The expression now becomes;

$25 {x}^{2} - 16 =( {5x - 4})(5x + 4)$

Therefore the correct answer is option A.

What is the equation of the line, in point-slope form, that passed through the points (-1,7) and (-2,3)

s2008m [1.1K]

Answer:

y-7=4(x+1)

Step-by-step explanation:

y-y1=m(x-x1)

m=(y2-y1)/(x2-x1)

m=(3-7)/(-2-(-1))

m=-4/(-2+1)

m=-4/-1

m=4/1

m=4

y-7=4(x-(-1))

y-7=4(x+1)
