HELP! PLEASE completing the square Solve 4x² =- 8x + 12
Could any of you help me?
@brookester6 could help me?
set it to 0
0=4x^2=-8x+12?
wait, thats if your factoring lol square each side
I'm not sure how to do that
X = -3 x = 1
What are the steps that I would take to get that answer?
thats factoring..
\[4x ^{2}=-8x+12\] \[4x ^{2}+8x-12=0\] Divide by 4 on both sides \[x ^{2}+2x-3=0\] \[x ^{2}-x+3x-3=0\] \[x(x-1)+3(x-1)=0\] \[(x-1)(x+3)=0\] So, x=1 or x=-3
Solve for x over the real numbers: 4 x^2 = 12-8 x Subtract 12-8 x from both sides: 4 x^2+8 x-12 = 0 The left hand side factors into a product with three terms: 4 (x-1) (x+3) = 0 Divide both sides by 4: (x-1) (x+3) = 0 Split into two equations: x-1 = 0 or x+3 = 0 Add 1 to both sides: x = 1 or x+3 = 0 Subtract 3 from both sides: Answer: | | x = 1 or x = -3
Aweosme! Thank you all so much. I appreciate it. Very helpful.
