DUIVING Qudulal Equations by Factorin
Question 3
A student solved a quadratic equation as shown here:
2x2 + 5x = 12
x(2x + 5) = 12
x= 12or 2x + 5 = 12
x= 12or 2x + 5 - 5 = 12-5
x= 12or 2x = 7
x= 12or x=?
x=1,12
Explain the errors in the process. Then correct the errors, and solve the equation.

d

step-by-step explanation:

given

y + 3 = - 4(x - 2) ← distribute the parenthesis

y + 3 = - 4x + 8 ( subtract 3 from both sides )

y = - 4x + 5 → d

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1
