The polynomial is a difference of perfect squares. use the formula a2 – b2 = (a + b)(a – b) to factor completely. 81x2 – 49 the value of a is . the value of b is . the product of the prime factors is .

The equation x2 – 1x – 90 = 0 has solutions {a, b}. what is a + b?

Find the value of the variable and the length of each secant segment.

Asap describe the transformations required to obtain the graph of the function f(x) from the graph of the function g(x). f(x)=-5.8sin x. g(x)=sin x. a: vertical stretch by a factor of 5.8, reflection across y-axis. b: vertical stretch by a factor of 5.8,reflection across x-axis. c: horizontal stretch by a factor of 5.8, reflection across x-axis. d: horizontal stretch by a factor of 5.8 reflection across y-axis.
