The solution of the given equation is -6 and 1.
<h3>What is Quadratic Equation?</h3>
A quadratic equation is an algebraic equation of the second degree in x. The quadratic equation in its standard form is ax² + bx + c = 0, where a and b are the coefficients, x is the variable, and c is the constant term.
Here, given equation:
(x+2)(x+3) = 12
x(x+3)+2(x+3) = 12
x² + 3x + 2x + 6 = 12
x² + 5x + 6 - 12 = 0
x² + 5x - 6 = 0
x² + 6x - x - 6 = 0
x(x+6) -1(x+6) = 0
(x+6)(x-1) = 0
Now, x + 6 = 0 or x - 1 = 0
x = -6 or x = 1
Thus, the solution of the given equation is -6 and 1.

Answer:
On the science test the point ( 0 , 424 ) the intercepts is bigger
Step-by-step explanation:
The relation hours spend vs science test score is
y = 6.5*x + 424
And the relation hours spend vs Maths test score is
y = 7.2*x + 34.7
Making x = 0 ( student does not study at all ) we get:
For science score test woul be
y = 0 + 424
In case of maths
y = 0 + 34.7
That mean student without studying will get better score in science.
The point ( 0 , 424) ( science ) represents the interception with y axis
in Maths case such point is ( 0 . 34.7)
