Q. Solve the system of equations.y=x2+14x−35y=6x+13Write the coordinates in exact form. Simplify all fractions and radicals.(______,______)(______,______)
Set Equations Equal: Set the two equations equal to each other since they both equal y. This gives us x2+14x−35=6x+13.
Subtract and Simplify: Subtract 6x+13 from both sides to set the equation to zero. This gives us x2+14x−6x−35−13=0, which simplifies to x2+8x−48=0.
Factor Quadratic Equation: Factor the quadratic equationx2+8x−48. We are looking for two numbers that multiply to −48 and add up to 8. These numbers are 12 and −4. So the factored form is (x+12)(x−4)=0.
Solve for x: Solve for x by setting each factor equal to zero. This gives us x+12=0 or x−4=0. Solving these gives us x=−12 and x=4.
Substitute x=−12: Substitute x=−12 into one of the original equations to find the corresponding y value. We'll use y=6x+13. This gives us y=6(−12)+13, which simplifies to y=−72+13, resulting in y=−59.
Substitute x=4: Substitute x=4 into the same equation y=6x+13. This gives us y=6(4)+13, which simplifies to y=24+13, resulting in y=37.
