Question

Use the graph of y = x2 + 7x + 12 to find the solution.

Answer 1

the solutions for x are when when y=0, ie when the line cuts the x-axis

Answer 2

the solutions also make the equation equal to zero\[y = x^2 + 7x + 12=(x+\cdots)(x+\cdots)=0\]

Answer 3

what ere the two x's that solve the equation?

Answer 4

here is the choose for the qh a) x = 3, x = 4
b) x = -4, x = 3
c) x = -3, x = 4
d) x = -4, x = -3
