Lin solved the equation 8(x-3)+7=2x(4-17) incorrectly. Find the errors in her solution. What should her answer have been?
Irina-Kira [14]

Answer: The correr solution is x=\frac{17}{34}

Step-by-step explanation:

Since the steps in Lin's solution are not shown, we are not able to find her erros. However, we can solve it step by step and find the correct result:

8(x-3)+7=2x(4-17)

Firstly, in the left part of the equation we have to multiply 8 by the numbers inside the parenthesis; and in the right side we have to solve first what is inside the parenthesis:

8x-24+7=2x(-13)

Adding similar terms in the left side and multiplying 2x by the number inside the parenthesis in the right side:

8x-17=-26 x

Isolating x:

x=\frac{17}{34} This is the correct solution

Given the equation (x+a)^2(x-2)=x^3+bx^2+12x-72 find a and b
GaryK [48]
Isolate the variable by dividing each side by factors that don't contain the variable.

a=-  \frac{ x^{2}-  \sqrt{( x^{3} + x^{2} b+12x-72(x-2)-2x} }{x-2} ,-  \frac{ x^{2}+  \sqrt{( x^{3} + x^{2} b+12x-72(x-2)-2x} }{x-2}

Solve for b by simplifying both sides of the equation then isolating the variabel.

b= \frac{12}{x}+ \frac{72}{ x^{2} }-2+2a- \frac{4a}{x}+ \frac{ a^{2} }{x}- \frac{2a^{z} }{ x^{2} }

Hopefully i helped ^.^ Mark brainly if possible
