How do you solve this equation step by step (3x-4)^2=20 - 24x

Possible intermediate steps: (3 x-4)^2 = 20-24 x Expand out terms of the left hand side: 9 x^2-24 x+16 = 20-24 x Subtract (20-24 x) from both sides: 9 x^2-4 = 0 Add 4 to both sides: 9 x^2 = 4 Divide b

Ive worked this question twice and gotten it wrong both times, but I dont know what Im doing wrong. i know it is (a x b) dot c I substituted vector PQ for a, PR for b, and PS for c, but my final answ

Solve equation (x+6)^2=16

how do you solve this step by step-(x+6)^2=16 you need to expand the ^2 (x+6) x (x+6)= x^2 + 12x + 36 ie. x^2 + 12x + 36= 16then u can c thatu can make a quadratic eq from the above eq. all u need

Express 4(tan^2) - 4(sec^2) as an integer

I need help! Ten points for right answer! Thanks!-4(tan²x) - 4(sec²x) = 4(tan²x - sec²x) = 4(sin²x/cos²x - 1/cos²x) = 4((sin²x - 1)/cos²x) = 4((1 - cos²x - 1)/cos²x) = 4(-cos²x/cos²x) = 4(-1) =

HELP! please! so confused:(

a) the equation 12x^3-23x^2-3x+2=0 has a solution of x=2. find all other solutions. b) solve for x, the equation, 12x^3+8x^2-x-1=0 (all solutions are rational and between +/- 1) okay so im in calculu

How do i solve this equation? please help :)

2x^2+x=x^2-2x+4 show me the steps Thank You:)-2x^2+x=x^2-2x+4; X^2+3*X-4 = 0 Quadratic formula: X = (-b ±√(b²-4ac))/(2a) = ( -3±√(9 +16))/(2) positive discriminant = 25; two real roots: X=-4 and 1

Can you solve for t? (At-B)/(C-B(1-3t)=4

Im assuming there is another close parenthesis on the right side of the 3t (At-B)/(C-B(1-3t)) = 4 multiply both sides by (C-B(1-3t)) At-B = 4(C-B(1-3t)) simplify the right side At-B = 4(C - 1B + 3B
