The quadratic formula consists of substituting the numerical values of the coefficients, performing the mathematical operations, and obtaining as, a result, two real numerical values if the equation has them. The quadratic formula is as follows: ...

1.1 has many ingredients and is based on the next five lemmas. lemma 3.3 let \(k-2\) be a multiple of 4, and \(g^*\) be a \(k\times k\) grid. if \((g^*,\varphi )\) is p -separated, then there exists an affine transformation \(\nu \) such that \((g^*[-1],\...
p(x)=0 (5x−3)(2x+9x+14)=0 (by(a)) 5x−3=0 or2x2+9x+14=0 92−4(2)(14) =−31 <0 So, the quadratic equation 2x2+9x+14=0 does not have real roots. Note that 35 is a rational root of the equation p(x)=0. Thus,the equation p(x)=0 has 1 rational root....
To solve this quadratic equation, we need to factor. We can brake the x2-2x-35=0 into two factors: x2-2x-35=0 (x-7)(x+5)=0 Then we set each factor equal to zero and solve for x: (x-7)=0 (x+5)=0 x=7 x=-5
Quadratic EquationThe quadratic equation is the one that has as principal exponent a two; we can also call it a second-degree equation. We can solve this by factoring in or applying the quadratic formula. We must identify the ...
