Question

Write the quadratic equation whose roots are -4 and -3, and whose leading coefficient is 1.

(use the letter x to represent the variable.)

Answer 1

`x^(2) + 7x+12=0`

Explanation:

Roots of the equation are -4 and -3.

Quadratic equation can be written as

`(x+4)(x+3)=0\\x(x+3)+4(x+3)\\x^(2) +3x+4x+12\\x^(2) + 7x+12=0`
