Answer:
y = x²+7x+12
Explanation:
Given equation is :
y = (x+4)(x+3)
We have to transform above equation into standard form.
y = ax²+bx+c is standard form of quadratic equation.
y = (x+4)(x+3)
Multiply each term of first parentheses to each term of second parentheses.
y = x(x+3)+4(x+3)
y = x(x)+x(3)+4(x)+4(3)
y = x²+3x+4x+12
add the coeficients of like terms
y = x²+7x+12 is standard form of given equation.
