(4x - 3)(2x + 3)
4x - 9 = 35 4x = 35 + 9 4x = 44 4x/4 = 44/4 x=11
x 4HowThe starting equation is: 4x - 9 7To solve, first add 9 to both sides:4x 16Now, divide both sides by 4:x 4
4x2 - 12x + 9 = 4x2 - 6x - 6x + 9 = 2x(2x - 3) - 3(2x - 3) = (2x - 3)(2x - 3) or (2x - 3)2
(2x - 3)(2x - 3)
There is a formula for factoring the "difference of squares." In this case, the answer is (9 - 4x)(9 + 4x)
y squared minus 9 (y*y)- 9 cannot be solved because there is no given value for 9.
Solve this problem -x squared -40x- 80 =0
(2x - 9)(2x - 9) or (2x - 9)2
(4x - 3)(2x + 3)
sqrt(4x+7) -4 = sqrt(4x-1) squared : (sqrt(4x+7) -4)2 = 4x-1 (4x+7) - 2x4xsqrt(4x+7) +16 = 4x-1 -8xsqrt(4x+7) = -24 sqrt(4x+7) = -24/-8 = 3 squared : 4x+7 = 32 = 9 4x = 9-7 = 2 then x=1/2
8x2 + 6x - 9 = 8x2 + 12x - 6x - 9 = 4x(2x + 3) - 3(2x + 3) = (2x + 3)(4x - 3)
Let 6x - 2x - 9 = a, where a is an arbitrary constant. Then 4x - 9 = a 4x = a+9 x = (a+9)/4
4x - 9 = 35 4x = 35 + 9 4x = 44 4x/4 = 44/4 x=11
x=9 squared
y = (4x+9)/(2x+3)2xy+3y = 4x+93y-9 = 4x-2xy3y-9 = x(2-2y)x = (3y-9)/(2-2y)So, inverse function is 3x minus 9 divided by 2 minus 27.
Sobtract 1 from minus 9 and get minus 10.
