each subinterval, and record the sign of the expression above each: The inequality does not include “equals,” so we do not inclu ...
the abterms from the numerator and denominator, leaving ab. c.First, cube the 4g^2 term. Cube the constant 4 and multiply the ...
b. 21 ( + ) = 21= 21 ( ) = 10 d.(2 + 3 x)^2 = 4 + (2)( 3 x) + ( 3 x)(2) + ( 3 x)^2 = 4+4 3 x+ 3x a. ( 3 + ...
c.Square both sides of the equation and then solve for x: 10–3x= x–2 (10–3x)^2 = (x–2)^2 10–3x= x^2 –4x+ 4 0 = x^2 – x–6 0 ...
Set 40 (Page 95) d.Apply the quadratic formula with a= 1,b= 0, and c= –7 to obtain: x= = = ±^ = ± = ± 7 a.Apply the quadr ...
c.First, put the equation into standard form by expanding the expression on the left side, and then moving all terms to the lef ...
c.Isolate the squared expression on one side, take the square root of both sides, and solve forx: –3x^2 = –9 x^2 = 3 x= ± 3 ...
a.To solve the given equation graphically, let y 1 = 4x^2 ,y 2 = 20x– 24. Graph these on the same set of axes and identify the ...
a.To solve the equation graphically, let y 1 = x^2 – 3x– 3,y 2 = 0. Graph these on the same set of axes and identify the points ...
ANSWERS & EXPLANATIONS– b.To solve the equation graphically, let y 1 = ^16 x^2 – ^53 x+ 1,y 2 = 0. Graph these on the s ...
Set 42 (Page 98) b.Observe that b^4 – 7b^2 + 12 = 0 can be written as (b^2 )^2 – 7(b)^2 + 12 = 0. Let u= b^2. Then, rewrit- ing ...
